Don't you love hand held cameras?  Nothing goes unnoticed.

Bruce Springsteen made a surprise appearance Sunday night at a Clarence Clemons tribute concert at the Wonder Bar in Asbury Park, New Jersey.

Wanna see it? The Boss joined J.T. Bowen and the Soul Cruisers, whose lead singer used to work on a side project with Clemons.  Bruce popped on stage and played for 45 minutes.

Clemons' son Nicky opened the concert with his own band.  Only about 400 people were in attendance to witness the show, but now the youtube crowd is watching.  The last time Springsteen performed in public was also a surprise appearance at the Wonder Bar -- at an April 2 gig hosted by singer Nicky Addeo.

Bruce may not be touring, but he can pop up anywhere!
