• Buzz in to guess mystery tracks and score bonus points for singing on stage
• DJ sets, dance-offs and mini-games keep the party going between rounds

Time Out says

Duo Clapham’s turning karaoke into a full-blown competition. You’ll join either the red or blue team, wave your glowsticks and battle it out across rounds of music trivia, surprise tracks and fearless sing-offs. There’s a live scoreboard to track every win, a host to keep the chaos moving and DJs spinning between rounds. Expect chants, challenges and non-stop energy — this is karaoke meets game show, and the only rule is to sing loud.
