After three glorious heats featuring plenty of crazy costumes, dodgy dancing and, er, interesting vocals, the final showdown is here, hosted once more by Mel and Sue.

Taking to the floor again are radio presenters Melvin Odoom and Rickie Haywood Williams, comedian Sara Pascoe and the Chasers plus the casts of Casualty and Holby City.

They’ll be joined by the winning act and runner-up from heat three. At the time of writing, it’s hard to imagine anyone beating the Chasers and their wonderful Wizard of Oz medley – who knew the scary quiz masters could sing so beautifully?

But you never know in this show… Utterly fabulous!
