And the No. 1 reason for U2 fans to stay up late...
David Letterman has just signed up the band for a weeklong stint at the home office.
Bono and the boys are scheduled as Late Show musical guests on five consecutive nights, March 2-6, as part of a massive publicity push for their new album, No Line on the Horizon. The Irish rockers' 12th studio effort is scheduled to drop March 3.
The five-night booking, a first for Letterman, comes on the heels of U2's rollicking performance of the single "Get On Your Boots" at last Sunday's Grammy Awards.
The last Late Show appearance for the Rock and Roll Hall of Famers was back in 2001 when U2 was making the promotional rounds for All That You Can't Leave Behind.
