I tried to come up with an answer posting on a couple of boards, but never found anything definite - the great Chicago blues drummer, Earl Phillips, who recorded with Wolf, was the drummer on all of the classic Jimmy Reed sides, and played on a number of Vee-Jay blues sides, may have recorded with Roy Eldridge in 1946 for Decca.
Earl Phillips is listed as the drummer on the "Hi Ho Trailus Boot Whip" session. Earl Phillips is a somewhat common name, but there can't be too many drummers named Earl Phillips. If the Eldridge Phillips and the blues Phillips are the same man, he's a candidate for this thread.
