Singer/actor Nick Jonas and his Hairspray co-star John Stamos stunned locals in a New York bar on Monday (10Sep12) when they stepped onstage for an impromptu jam session.
The pals headed to The Bitter End in Manhattan and decided to surprise the crowd by showing off their musical skills, with Stamos rocking out on drums and Jonas taking control of the microphone.
They were joined by a few extra friends playing guitar and saxophone and treated their audience to renditions of Frankie Valli's You're Just Too Good To Be True and the Stevie Wonder classic Superstition.
