As you know, the Foo Fighters are out on tour. What you might not know as they have been having a blast and having fans come up on stage and sing the first verse of "haven't met you yet," Michael Bublé's 2009 hit single. John Freese's had a moment during each concert where he plays a medley of songs from other artists and bands he has worked with, like Michael Bublé. At their latest show, there was a "super fan" in the audience holding up an 'I heart Bublé' sign. Dave Grohl called them up to the stage, and it was none other than, THE Michael Buble! Dave said HE better know the word to this one. Check out Michael performing with the Foo Fighters!
