British actor Jude Law helped kick off the London 2012 Festival as host of a peace concert in Northern Ireland on Thursday.
The Alfie star was emcee at the Peace One Day gig in Londonderry's Ebrington Square, where singers Pixie Lott, Newton Faulkner and Imelda May put on a free show for thousands of fans.

The event marked the start of the London 2012 Festival, a 12-week programme of arts events running in association with the London Olympic Games.
Law says, "Any opportunity for people to get together and have fun is a good thing. If you go back to the origins of the Olympics, it was always about truce as well and that's why it seems so apt that Peace One Day, as an organisation, is working alongside the 2012 Cultural Olympiad."
Sir Elton John has been booked to perform at a September Peace One Day concert at London's Wembley Stadium to mark the culmination of the campaign.
