Summary Jay Blade and the Repair Shop team review the way that music instruments that have helped shaped the way music is played live. First up is a pump organ brought in to the barn by music teacher Marion Stanley and previously owned by Marion's dad, who grew up in the East End. Jay tells the story of how instruments like this one used to be played live in places like the East End of London to entertain people. With no TV and no other access to live music, street parties and gatherings were common ways to celebrate everything from Christmas and birthdays - a tradition that continues to this day on big occasions like the Queen's jubilee. Live music has also been a form of solace in trickier times, as witnessed by an accordion brought in by William and his family. William's mum, Iris, used to play it during the Second World War to entertain families as they waited out German air raids in underground shelters. After the war, the story of musical instruments and live performances took another turn thanks to the invention of amplified instruments, such as the bass brought in by Danny Wilson and his mum, Margaret. They also bring a touch of pop glamour to the barn, as Danny's dad was a member of 1970s band Hot Chocolate. Danny wants to learn the bass, but it doesn't play properly, so it's over to restorer David Kennett to work his magic.
