Ed Sheeran did a great job covering this Bob Dylan classic, all for the cause.

If you don't know of Ed Sheeran, get to listening! Ed is gaining quite the popularity with his tunes 'The A Team' and 'Lego House.' Oh yeah, he's also on tour with Taylor Swift.

He did a bang up job on putting his spin on the Bob Dylan tune, 'Masters of War.' He and a bunch of other artists and bands have joined the 'Agit8 Project' which aims to influence leaders at next weeks G-8 summit. The project is backed by The One campaign which was set up by u2's, Bono.
