Gareth Malone stopped by the Classic FM office to give a choral workshop - and we filmed the results!

With a little help from his Voices choir, Malone gave the staff of Classic FM a vocal workout and led them in a performance of Radiohead's 'No Surprises' in just 20 minutes - warm-ups and rehearsing all the individual parts included!  

Watch the video above to see how presenters like Jamie Crick and the rest of our behind-the-scenes team got on when confronted with sight-reading and the expertise of Gareth's choir to compete with.

Gareth and his choir were in the office to talk about their debut album, which takes a number of popular and modern songs from the pop world and gives them radical choral makeovers.
