That's a lot of U2

Timed with the release of U2's new album, "No Line on the Horizon" on March 3, the band will spend a five-day residency at "Late Night With David Letterman," playing the show every weeknight from March 2 through 6.

If you haven't caught it, watch the video of the newly released single, "Get On Your Boots." It's the same song the band played at the Grammy's last week.
