It’s not every night you get to be serenaded by U2’s Bono before you go to bed (unless, of course, you’re Mrs. Bono, in which case, disregard what I just said). But this week was the exception to the rule. Bono, the Edge, Larry, and Adam played five nights this week on the Late Show With David Letterman to promote their new album, No Line on the Horizon. When I heard about this stunt, even I, as a fan, was apprehensive. Would it be overkill? On the contrary, it made me look forward to staying up until the wee hours and inevitably having a hard time falling asleep after. Between the comedy bits, which included the guys shoveling snow, answering reader mail (you have to admit, the guys are good sports), and getting their own street for a week, it was a fun few days for U2 (and Letterman) fans.

So how did they wrap things up? With the first single off the album, “Get On Your Boots,” a song I was iffy on the first few listens but have ultimately warmed up to. The performance was better than their outing at the Grammys (maybe because Bono went sans eyeliner this time), and I couldn’t help but sing along with the line “Let me in the sound!” It wasn’t nearly as good as this week’s “Breathe” but it definitely got my toes tapping more than “I’ll Go Crazy If I Don’t Go Crazy Tonight.” Friday’s performance: B. The week overall: A-

What did you think, PopWatchers? What was your favorite part of U2 week? Did Friday night send U2 out on a high note?
