Episode 5

Celebrity investigators Jimmy Carr, Alison Hammond and Amanda Holden try to help best friends Esslyne and Nkechi from Kent to tell the difference between good and bad mystery singers without ever hearing them sing a note. With £10,000 on the line, and a line-up including a yoga instructor, a ringmaster and a milkman, they attempt to weed out the bad singers based on a series of clues, interrogations and lip-sync performances. Special guest Claire Richards from Steps brings her pop knowledge to help spot the imposters, and all our stars take on one of Steps' iconic dance routines.
