Gareth Malone talks about the official CiN song

It wouldn't be Children in Need without an official song, and this year TV choirmaster Gareth Malone has stepped up to the challenge.

He had to pull together a group of children and celebrities to record and perform a single for Children in Need.

The choir are singing a cover version of Avicii's smash hit Wake Me Up, and it is doing well in the UK music charts.

Some of the celebrity singers include CBBC's Radzi Chinyanganya, Bake-off presenter Mel Giedroyc and Strictly meanie Craig Revel Horwood.

Ricky caught up with Gareth to find out how the rehearsals are going.
