Bon Jovi @ Super Bowl XLIX
 

No, the band didn't play the halftime show and Jon wasn't at the stadium to witness his buddies Bill Belichick and Bob Kraft winning their fourth ring, but somehow Bon Jovi made an appearance at the game last sunday in Glendale: :D

(The stadium screens were announcing "This is our house" as the Patriots TD song, it was clearly visible during the Pats extra point kicks in the 4th period).
