U2 frontman Bono got together with a handful of other musicians on Christmas Eve to perform on Grafton Street in Dublin. Check out the clip below. Joining Bono were Glen Hansard of the Swell Season, Damien Rice and Mundy. The men were raising money for Simon Community, an organization benefiting the homeless in Ireland. The performance lasted almost an hour, and the songs performed included Ben E. King's "Stand By Me", U2's "One", and Bob Dylan's classic "Knocking on Heaven's Door".
