U2 returned to the MTV airwaves Monday with the premiere of "Sweetest Thing," the band's latest video for a track from its upcoming greatest hits compilation.As we previously reported (see "U2 Joined By Boyzone For 'Sweetest Thing' Video"), the clip for the song features fellow Irish music posters Boyzone, although the vocal group does not actually turn up on the song. "U2: the Best of 1980 to 1990," the band's first greatest hits collection, features well-known gems like "Pride (In the Name of Love)," "With or Without You," and "Sunday Bloody Sunday." The album also carries "Sweetest Thing," a b-side that frontman Bono wrote for his wife Ally more than a decade ago. "It was written during the album sessions for 'The Joshua Tree,'" Bono explained, "and it was Ally's birthday and I didn't make it [home] for the birthday. So, I wanted to write her
a little sweet song, but it ended up a little bit sour as all the best love songs are. I was like, 'I can't write just straight love songs, they make me want to throw-up.'" [28.8 RealVideo]Longtime U2 fans may recognize the young man on cover of the upcoming compilation. It's Peter, the younger brother of a friend of the band whose photo graces the covers of two of the band's earliest efforts, "Boy" and "War."
