The Song:

We added this to the setlist, it was a funk jam that Beck played live 3 times during one week of the Vultures tours. (Since Beck at one of them ad-libbed something about doing the boogaloo.)

Listening to one though, I realized it was actually "Bra." I haven't verified the other 2 times, but due to their close proximity in date, I have changed them all to refer to "Bra" and eliminate this song.
