Welcome to Chartjackers, where you can follow the journey of Jimmy, Johnny, Alex and Charlie as they try and crowd source a number one single for charity! They've only got ten weeks to get a song written, recorded, performed and released and they need as much help as they can get.

Check this channel each week for exclusive video blogs from the four Chartjackers, and for the weekly mini documentary episodes we will be posting on saturday afternoons. If you live in the UK these eps will be on BBC2 in the BBC Switch strand at 12.50 each week.

There's more information at http://www.bbc.co.uk/chartj...

You can follow all the action in bite sized chunks on our twitter feed here: http://www.twitter.com/bbcc...
