Query: They've finally found what they've been looking for

U2 finally found what they've been looking for. Grammys for their THE JOSHUA TREE album. The album sold seven million copies in 1987,the year it was released. A worldwide tour followed the release of this album inspiring RATTLE AND HUM,both the movie and the follow-up album. Live versions of I STILL HAVEN'T FOUND WHAT I'M LOOKING FOR(with a gospel choir) and BULLET THE BLUE SKY appeared on RATTLE AND HUM. The band dedicated THE JOSHUA TREE to their friend Greg Carroll,who died in 1986 at only age 25 or 26. The album notes give his birth year as 1960.
