Norwich Rock Choir and Helen McDermott take part in a flash mob choir.

Every Tuesday I shall be showcasing a new gem from YouTube's vast library, but with a Norfolk twist. This week's video is from YouTube user WAVUK.

In aid of Comic Relief 2013 television presenter Helen McDermott along with the Norwich Rock Choir took part in a flash mob at the forum. Singing along to 'Proud' by Heather Small, the choir wowed the crowds and rose a lot of money for comic relief.

If you have seen a YouTube video you think should be featured - whether it's weird and wacky, informative or sporty - and is Norfolk focused, please contact me via Emily.Dixon@archant.co.uk
