As we type this, U2 is performing a dress rehearsal for their upcoming 360 Tour in Barcelona, and the good people at U2gigs.com are live-tweeting the set list. The show is only halfway through at the moment, but they have been focusing mainly on material from their last three albums, though they have revived "The Unforgettable Fire," and Bono snuck in a snippet of Michael Jackson's "Man in the Mirror" after a rendition of the soulful oldie "Angel of Harlem."
