Paddy McGuinness hosts as sisters Dominique and Tahiela from Leeds use their detective skills to spot the fake singers. They are assisted by celebrity investigators Jimmy Carr, Alison Hammond and Amanda Holden. This week, Andy Bell from multi-million-selling band Erasure joins to help identify the imposters.

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, but with a line-up including a barber, a salesman and an actress, they may have their work cut out! In the end, the last mystery singer standing will reveal if they are a good or a bad singer in a duet with Andy on the Erasure classic A Little Respect. If the players picked 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!

West End star Layton Williams joins the celebrity investigators to help mother and daughter Maryanne and Chloe from Poole try to spot the imposters, but with a line-up including an air hostess, a cabbie and a bartender, they may have their work cut out.

The last mystery singer standing will reveal if they are a good or a bad singer in a duet with Layton, resulting in either a magical musical moment or a comedy collaboration on the Motown classic Ain't No Mountain High Enough.

If Maryanne and Chloe correctly identify a good singer, they win £10,000 - but if a bad singer manages to fake it all the way to the end, they steal the money.
