It's an upbeat Bill Murray, in animated form, singing as apart of a new video from David Letterman's Late Show band.
"Happy Street" is a song on the new album from Paul Shaffer and The World’s Most Dangerous Band. Sung by Bill, Murray's magical song helps prevent an armed robbery, gets people to come out of a bar and even makes a man who was hit by a car "smile." The video makes references to Murray's movie career as well.
The self title album comes out on Friday, March 17th.
