Tom Waits "Take One Last Look" (live on 'Letterman')
As David Letterman prepares to end his run as the host of The Late Show next week, he's going all-out with a seemingly endless star-studded list of guests. The musical performance on last night's show (May 14) came courtesy of Tom Waits, who delivered a brand new tune called "Take One Last Look."
 
Fittingly, the gravelly voiced singer dedicated the track to Letterman, who watched the performance while handcuffed to George Clooney. It's a bittersweet number about saying goodbye, and serves as a touching and fond farewell from Waits to the late-night host.
