Olly Murs Christmas sing-a-long

Olly Murs is flexing up his vocal chords for the Big Christmas Sing.

The X Factor finalist will be belting out festive favourites alongside X Factor reject John Adeleye and Britain's Got Talent finalist Faryl Smith at the Christian Aid-hosted annual singing event, which takes place at the Old Spitalfields Market in London tonight.

Olly, who will also turn on the market's Christmas lights, said: "The Big Christmas Sing is a great way to have fun with your friends and get into the festive spirit while raising money for a good cause. I'm really looking forward to a good sing-along and to turning on the Christmas lights at Old Spitalfields Market."
