Summary Last week, four semifinalists were sent into the next round of the competition, and Tuesday night brought a chance for 12 more contestants to claim four more spots.

Howie kicked off the night with a David Hasselhoff joke, saying that choosing last week between RNG and Future Funk, two kids dancing groups, was like David Hasselhoff deciding which daughter to share a burger with.

Cheer SF: The group leader said Cheer SF has been around for 30 years. In the intro package, Piers said his problem with the group was that they were mostly blokes and a cheerleading group should have more ladies. But the group is aiming to break down stereotypes. Not surprisingly, Piers buzzed them. Sharon followed, but Howie let them finish what wasnt a particularly bad performance. It just wasnt all that impressive. Piers said he simply doesnt get cheerleading as a form of entertainment in a show like this. He said he wanted to go to sleep. Sharon loved their enthusiasm, but thought that such a mature group should have presented more moves theyve never seen before. Howie said it wasnt as technically amazing as hes seen cheerleading done.

Alice Tan Ridley: Sharon said in the intro package that she couldnt believe Alice Tan Ridley hadnt been discovered yet. Alice said the last time she was in L.A. was to be with her daughter, Gabourey Sidibe, at the Oscars. But her own dream has yet to come true. She sang Midnight Train to Georgia. Sharon said she wanted to be on that train with Alice, and she called her an amazing woman. She told Alice she did it right -- you took care of your family and now youre taking care of you. Piers said Alice has everything the show is looking for, and said it might not be long before Alice is on a red carpet again, but not as Gaboureys mom. Instead, folks might be asking Gabourey if shes Alice Tan Ridleys daughter.

Mona Sampath Dance Company: The group wanted to bring its updated interpretation of Bollywood, and said Vegas needs it. Their leader said their version of the dance was more than just a guy and a girl dancing around a tree. Howie said the judges loved their connection between Bollywood and modern dancing, but this routine wasnt as good as what hed seen before. There was no wow moment, he said. Piers told them to relax and said Howie doesnt know anything about Bollywood. Piers said it was miles better than the audition. Sharon said it was very, very exciting to watch. She said their joy was infectious, but said she wanted to see some more traditional dance next time.

Iron Horse: A bluegrass rock trio that didnt get a lot of face time during the audition process mixed their music with spectacle, by doing tricks like standing on their bass. The performance seemed a little thin and Piers buzzed them. He said the stage seemed too big to them and it seemed like they went backward, becoming a good bar band and not good stage band. Piers also said the singer was no good. Sharon said they should have cut the tricks because it distracted from the music. Howie took the other course and said that if they wanted to keep the tricks they needed to dedicate more of the 90 seconds to one or the other.

The Strong Man: After some impressive auditions, The Strong Man vowed to bring something big to the Hollywood stage. He was going to work with over 2,000 pounds and raise the stakes on the danger. Nick gave the dont try this at home warning. He had a whole bit about his solution to the parking problems in Los Angeles, lifting a motorcycle out of the way, then flipping a car over. Sharon said she thought that with a big Vegas production, he could do more outrageous things. Howie thought it was amazing, even though he didnt know what it was. Piers said he didnt know how impressive it was, saying, There are people in South Central L.A. doing that every night. Piers then told The Strong Man he wasnt the strong, dynamic entertainer needed for Vegas. (As a side note, they showed the production crew removing the car from the stage, and it took almost a dozen guys to flip it back over).

Ronith: The impressionist who constantly vowed to be back, was back again. He switched things up during the Vegas round of the audition, taking Piers advice in getting rid of the impressions. But Howie and Sharon wanted them. In his most awkward performance yet, Ronith brought back the impressions. Piers buzzed him almost immediately. Sharon buzzed him later. The crowd sat in stunned silence as Howie gave a standing ovation. Howie said Piers didnt get it, that bad is good. Ronith finally understood what Howie was trying to say and agreed, bad impressions make you laugh. Piers said Ronith is just bad, not brilliant. Sharon was just confused. As Nick read out Roniths phone number for the voters, Piers pleaded, No!

Hannibal Means: Howie sang Hannibal scares him, and called the singer a human thrill ride, but clarified, I dont want to ride him. Hannibal went on some speech in his intro package, talking about how his singing is saying yes to life, and he invited everyone to say yes with him. He sang Elton Johns Circle of Life, complete with Lion King-inspired dancers. Piers said it was so crazy, and yet, underneath all the madness, theres a great singer in Hannibal. Sharon said Hannibals voice is so rich and amazing, she was just upset that he didnt knit her a hat. Howie just wanted to know what planet Hannibal was from.

Wreckless: The dance group that was used to performing on the streets and once struggled to find a place to practice faced the biggest opportunity of their lives, on the biggest stage of their lives. They put on a dazzling performance that earned big cheers from the crowd. Sharon said it was amazing to see them pull off such a highly choreographed routine. Howie said he didnt sense the edge they had before. Piers said he looked for acts who can fill a big stage, and he said he completely agreed with Sharon.

Lil Chris: Chris talked about taking a chance with Tuesday nights performance, going with something more current, singing Ne-Yos Closer. With two backup dancers, he showed some moves and some vocal chops. Howie was impressed at his level of talent at age 12. Howie told him to put the time in to practice and make it perfect. Piers was surprised to agree with Howie and said he was worried that this opportunity had come a little too soon for him. It wasnt quite there, Piers said, but noted that Chris is a very exciting prospect. Sharon said he held his own and that he did fantastic.

AscenDance: The husband-and-wife couple said they were training incredibly hard and introduced two more dancers into their act. Howie said their act was one of the most dangerous because if the wall-climbing dancers lost one grip, it was all over. They put on a mesmerizing performance that wowed the crowd. Piers said that if someone explained to him that the act was to prance around on a wall to Snow Patrol he wouldve thought they were mad. He was stunned, though, and called it a beautiful thing to watch. He also said he could see them making it even bigger on a Vegas stage. Sharon agreed it was endless what they could do with the act in Vegas. Howie agreed it was unique and the dancers were passionate.

Antonio Restivo: The fiery illusionist with a heart of gold became emotional in the intro package when talking about his father, who passed away but was 100 percent supportive of everything he did. He was raising the danger stakes and said he couldnt wait for everyone to see it. He sent flames flying as he moved an assistant from one cage at one end of the stage to the other. Sharon said it was hot and he used the time very week -- and, of course, the music was just sensational. (It was Ozzy). Howie said that act was consummate Las Vegas. Piers said the big question is whether an illusionist has a big enough performance to headline in Vegas, and he believed, after seeing Antonios performance, that Antonio had it.

Michael Grimm: After a tough childhood that included being raised by his grandparents, Michael Grimm was ready to give it all that he had. He sang Al Greens So Tired of Being Alone. Howie said Michael is his favorite singer in the whole competition, saying he wanted to be the first customer to buy his album. Piers said Michael was a work in progress but noted hes a very, very good singer. He told Michael to connect with the audience more by having more confidence. Sharon said she could genuinely see and hear the hard times Michael has been through in his singing.
