TERM: 'U2'

"With or Without You" is the lead single from U2's 1987 album, The Joshua Tree. It has since become highly-acclaimed as one of the band's most popular songs. Released as a single in March 1987, it became the group's first American #1 hit, spending three weeks at the top; it also reached #4 in the UK.

"U2 3D," a film of the band's 2005-06 Vertigo tour, shot at several shows in South America with new 3-D technology. "It's kind of horrific," to see himself on stage in 3-D, said Bono.
