Jonas Brothers Jam with John Stamos During Intimate, Impromptu NYC Gig [VIDEO]

While Kevin Jonas is busy off filming E!'s hit reality show "Married to Jonas," brothers Nick and Joe Jonas were performing a small and intimate impromptu jam session with actor John Stamos at the NYC rock 'n' roll club The Bitter End. Nick and Jonas shared vocals while Stamos took over the drums, performing the classic, sultry hits "Superstition" and "Can't Take My Eyes Off Of You."

The two former Disney stars and former "Full House" star surprised the crowd gathered at the underground rock venue with a chill and relaxing set. Check out a video as the unlikey musician trio performs the 1967 Frankie Valli classic Can't Take my Eyes Off of You."
