Just watched The Gene Krupa Story last night, starring Sal Mineo. It sure looked to me like Sal was doing his own drumming ~ that would be hard to fake, after all ~ but in the big on-stage performace near the end of the film, it looked like it might have been faked; audio and video didn't seem to synch as perfectly as in the eaalier sequences.

Maybe Sal was a good enough drummer to actually play all but the most demanding parts ~ ??
