Last night, MGMT performed at the Egyptian Room, Old National Centre in Indianapolis when the crowd was treated to a special guest performance by the Colts' Andrew Luck and Anthony Costanzo on the cowbell. According to the folks on Twitter, Luck came onstage unannounced and served as the band's backup percussionist. And if that doesn't make the 24-year-old quarterback seem a whole lot cooler in your eyes, it seems that after the concert, Luck went to downtown Indy to grab a bite at Steak 'n Shake like your everyday, regular dude, even though he's, you know, kind of a big deal.
