WHO LET THESE GUYS IN THE SUPERBOWL?

So I'm sitting here watching Bruce Springsteen and the E Street Band perform at the Superbowl halftime show and who do I see on stage but Max Weinberg from Conan O'Brien, and Steven Van Zandt from the Sopranos! Little did I know they ARE the E Street Band! What the hell, how come no one tells me about these things? I also saw La Bamba from Conan in the mix, but I think he just snuck on there. Ok, that's enough it's making me feel a little nauseous talking about it for so long.
