The SFFMC maintains a webpage and mailing list. Eric Hoffman has been running slow jams at his home and posts them to that list. His e-mail is ErikThor@aol.com.
Kapish 'slow jam'? It is a gathering where tunes are requested and then played slooooww so you can learn them and is usually attended by a number of different instruments, including your namesake and fiddles. There is also EB pickin and singin still, I think. At any rate, posting to that list ought to find you what you want.
To sub to that list, e to "harmony-request@idiom.com" and say 'subscribe' in the body of the copy
or "http://www.idiom.com/harmony" for the webpage
