Modesto Bee carried the obituary.
It reads in part:
He recorded with Little Walter and Ray Charles and died Thursday, October 8, at the age of 70 from cancer.
A bit more can be found from an AP obituary.
According to that he also played with Howlin' Wolf and Monk Higgins and "recorded and wrote several songs including "Black Fox," "At the Drive-In," "Bluesology" and the blues instrumental, "After Hours."" With Little Walter he played on "My Baby's Sweeter," "Crazy Mixed Up World," "Everything's Gonna Be Alright," and others with Luther Tucker being also on those sessions.
He also played with John Mayall in the Jazz Blues Fusion Band that included Blue Mitchell and Clifford Solomon. Funny how this great guitarist is never mentioned when folks talk about Mayall's guitarists, nor is this band which was one of Mayall's more interesting ones. He was also on Louis Myers "I'm a Southern Man" album and sessions with Jimmy McCracklin (Minit) and others.
