I recently came across this shot of Rudy that I took, one of a series of portraits I did of him in the mid 1980's. This was taken in his little store in San Francisco where he spent much of his time composing. You can see the sheet music laid out in front of him. He had lots of time to write, as I never saw many customers there.
I had the pleasure of playing with him in the Berkeley Mandolin Ensemble during that time He was much loved by fellow players and audiences alike. There is a short biography of him on David Grismans' site: http://www.dawgnet.com/acd_html/artists/cipolla.html
