I really don't think the bearded guy in front is Garcia! Anything is possible with make-up and camera tricks though I guess
It clearly isn't a conspicuous appearance I guess. I imagine he would have had a beard in 76-77 though. I haven't seen the Bernadette Peters - Andy Kaufman movie to my knowledge; have to keep that in mind....I had a crush on Bernadette as a youngster. She's cute and seems to have a great personality.
