Jimmy Fallon asked U2 to spend a week sitting in on 'The Tonight Show,' and through the wonders of modern technology, that invitation has been extended to the band's fans.
As if being ripped apart by both Ozzy and Sharon Osbourne wasn't humiliating enough, now U2 are being slammed by the Foo Fighters' drummer for having the audacity to give away their new album to anyone with an iTunes account two months ago.
U2 refused to play by the rules when they partnered with Apple for the shocking giveaway of their 'Songs of Innocence' album, and it sounds like they might also plan to defy a few expectations with their 2015 tour.
During the last week of October 1988, U2‘s anticipated concert movie ‘Rattle and Hum’ was released in their native Ireland.
