Thanks for posting that. It contained the answer to my question above:
December 14, 1974 - MULTIPURPOSE ROOM, STUDENT CENTER, RUTGERS UNIVERSITY, NEW BRUNSWICK, NJ (after the Billy Joel appearance)
No set details known. Following his guest appearance with Billy Joel at the main Rutgers concert auditorium (see above listing) Springsteen walks across campus to the school’s Student Center and jams with
Sid Gottlieb’s band
Heavy Trucking. This took place after midnight, so technically speaking it was on December 15. Heavy Trucking had previously opened for Bruce at a concert at Rutgers on
April 1, 1973. Peter Wyman, who worked for Rutgers University Major Events Programs at the time, has commented to Brucebase “after the (Billy Joel) encore Bruce was by a back door and asked me what the quickest way to the Student Center was. I walked him there and he told me he wanted to play with Heavy Trucking, they did five or six songs together”.
