All Star Musicals (STV, 6.40pm-8.30pm)

He’s best known as a cricketer, but Andrew ‘Freddie’ Flintoff is in the process of re-inventing himself as an all-round entertainer with a role in the new musical Fat Friends. So really, who better to present this one-off special which sees a group of famous faces, not normally known for their allsinging skills, taking on an iconic musical number at the London Palladium Theatre? Tony Robinson, Denise Lewis, Nicky Campbell, Sally Phillips, soaps stars Lucy Fallon and Michael Parr and Rebecca Front all have proven performance skills, but this is still a nerve-wracking challenge.

Maigret in Montmartre (STV, 8.30pm-10.25pm)

The detective’s latest case presents him with a baffling conundrum in the shape of two seemingly random murders, with the victims coming from very different ends of the social spectrum – one is a countess, and the other a showgirl. His investigation soon reveals a dark secret that is an unexpected connection.

Mary, Mel and Sue’s Big Christmas Thank You (BBC1, 7pm-8pm)
