Thanks, Peter. I shoulda known it was Jimmy Spruill. Wild Jimmy was quite an electric guitarist, to be sure. And like Mickey Baker (not to mention the great Grady Martin), his work can be heard on a lot of records recorded by others in the 50s and 60s. There was a collection of Wild Jimmy Spruill's recordings that came out on CD last year. I think it was called "Scratch 'n' Twist." But unfortunately it doesn't include the songs with Tarheel Slim (or Wilbert Harrison's "Kansas City," which features a fine solo by Spruill).
