The Frisco Fire Band consisted of Faith Petric, Kate Brislin (who played banjo and sang), Tony Marcus (tall fellow who played every instrument and sang in a low voice) and Peter Kessler (singer and guitarist, probably played some mandolin). I don't know who John and Bob were. There may have been subsequent iterations - sounds from the above postings like one of them included Larry Hanks (jews harp player who wrote Apple Pickers Reel) and his (at that time) wife, Laura Smith. The original FFB toured England in the early 70s, I believe, or possibly the late 60s. Faith Petric died about a month ago, at age 98, mind still pretty sharp. There will be a memorial for her at the Freight & Salvage in Berkeley on Weds. Jan. 15, and the Frisco Fire Band will be playing (Kate, Peter and Tony) along with many, many others. You can watch it live on Concert Window: http://www.concertwindow.com/shows/faith-petric-memorial
This is LIVE streaming, it is not archived, you must watch as it is happening. Among the participants are Frankie Armstrong, John McCutcheon, Ronnie Gilbert, Larry Hanks, Nancy Schimmell, Flying Karamozov Brothers, Sylvia Herold, and others. It will be a true celebration of Faith's long and rich life.
