I learned SF Bay Blues from the jazzy version by Richie Havens. Havens had a very original guitar style and played in open tunings, I adapted a progression from the Mickey Baker book in standard and have been playing it for more than a half century. SF Bay Blues
I've also been playing Ninety Nine Years and One Dark Day for a long time and just found out recently that this song, which has become a Bluegrass standard, was written by Fuller.
