Greg, Daisy, Noel and Jamali are making some Christmas noise in this special edition of the music-based panel show, with the gang joined by big-collared funnyman Harry Hill, Little Mix superstar Leigh-Anne Pinnock, and Kaiser Chiefs frontman and Yorkshire Tea enthusiast Ricky Wilson. Plus, there's special appearances from 100% of DJ Luck and MC Neat, two fifths of 5ive, two sevenths of The Wurzels, and one half of Blazin' Squad's remaining squad.
