Beastie Boys

Did anyone catch the Beastie Boys performance on Letterman? It was very cool. They started off outside and walked down the sidewalks as the camera rolled in front of them and then worked their way down the street, through a side door and into the studio finally, where they emerged onstage. It was pretty cool. (Maybe they walked down from the MTV Studios because the Web site says they were on MTV at 11:30 also.) Plus, I liked their song, too, and I haven't really liked any rap song since... well, maybe since "Sabotage." It did seem like the guys were a little out of breath after all that walking, though, but I guess that is to be expected. I mean, they are in their 30s right?
