Ed surprised his UK fans by turning up on stage to perform a duet with Taylor Swift at CapitalFM's Summertime Ball.

Head over to the CapitalFM website to watch them performing to a packed Wembley Stadium.

Ed has recorded a version of Bob Dylan's protest song 'Masters of War' for the agit8 campaign.

Agit8 is a campaign from one.org and includes artists from all around the world recording their favourite protest songs in order to build pressure for action against extreme poverty in the lead up to the G8 summit.
