Paddy McGuinness hosts as celebrity investigators Jimmy Carr, Alison Hammond and Amanda Holden help best mates Anton and Duban from London try to tell the difference between the good and bad mystery singers, without ever hearing them sing a note. With £10,000 on the line, the players attempt to weed out the bad singers based on a series of clues, interrogation and lip-sync performances. When only one mystery singer is left standing, they reveal if they are a good or a bad singer in a duet with guest star Fleur East, resulting in either a magical musical moment or a comedy collaboration! If Anton and Duban pick a good singer, they win the money, but if a bad singer manages to fake it all the way to the end, they steal the £10,000. This time, the line-up includes a singing acrobat, a princess and a karate champion.
