The guy in jeans playing the violin...

When Harry follows Adrian into the vest pocket park, through the tunnel under the waterfall, there's a guy playing a violin. That's no extra playing a part; he was a genuine New York character in the '70s. One never knew where one would run into him, though his favorite spot was in the Fifth Avenue subway station, on the IND E and F lines. He could frequently be found there, playing his violin at the top of the escalator. I think his name was David, and sadly, he has no credit here on IMDB. Whenever I see Last Embrace, I wonder what became of him. Anyone else here remember him?
