Abba. Junk food. Watching Jeremy Kyle. Thwacking dawdlers on the Northern Line over the back of the head with a copy of Time Out before running away, laughing manically. We've all got our guilty pleasures, and this hugely fun night celebrates the musical side of them. It's a high-quality but ultimately cheesy party of pop, disco and, crucially, soft rock, where you can hear anything from Hall & Oates and Journey to Take That and Joan Jett. Leave your hipster credentials at the door, dress up and get guilty!
