I originally heard of him on a CBS sampler album called Rock Machine Turns You On in about 1968 playing Statesboro Blues and subsequently used to play that and Diving Duck Blues in a band I played in in about 1970.

As an aside it's a good sampler and encouraged us to buy five of the full albums afterwards-
1. I'll Be Your Baby Tonight - Dylan, Bob
2. Can't Be So Bad - Moby Grape
3. Fresh Garbage - Spirit (1)
4. I Won't Leave My Wooden Wife For You Sugar - United States Of America
5. Time Of The Season - Zombies
6. Turn On A Friend - Peanut Butter Conspiracy
7. Sisters Of Mercy - Cohen, Leonard
8. My Days Are Numbered - Blood Sweat & Tears
9. Dolphins Smile - Byrds (1)
10. Statesboro Blues - Taj Mahal
11. Killing Floor - Electric Flag
12. Nobody's Got Any Money In The Summer - Harper, Roy
13. Flames - Gantry, Elmer & Velvet Opera
14. Come Away Melinda - Rose, Tim
