Oh my god. That guy came out of nowhere. So much for the security watching out behind the band.
I bet it was some disgruntled Jay-Z fan. There was that one dispute Gallagher had having Jay-Z perform at this one concert in the U.K. (don't remember the name of it though).
Then again, if Noel Gallagher was anything like the comic Gallagher, he would've been prepared for that attacker with a trusty mallet or something.
