Interesting thread here.
I remember seeing Hammond, David Garthwaite for Joy of Cooking and Annie Johnson do a terrific impromptu version of the old Fiesta hit "So Fine" in 3 part harmony. What a lively and great coffeehouse that was at the very beginning of the 70's...the guy went on to write some creative stuff, gathered some good musicians around him, put out an interesting album on a shoestring (in all probability), played a bunch of gigs around California with that bunch. Then I saw him do a solo night at the Freight with a bunch of new material. Then he just vanished. I always thought something dire had befallen him. If he has more recorded material out there, I'd like to hear it
