Charlie: I'm impressed with your persistence!

Pitt Kinsolving is mentioned 13 times at www.songmakers.org. (Click here for Google's list of specific pages.) He has even served on the board of directors of that organization.

He is also president of the board of the Topanga Banjo Fiddle Contest & Folk Festival.

He is also a member of the Hollywood Sapphire Group ("a social organization … all of its members are associated with the sound recording industry or its allied fields").

It seems to me you would have a good chance of contacting him through one of those organizations.
