Larry, if you haven't found the right version yet, let me know. The correct title is "But I Do" written by Robert Guidry and Paul Gayten, and recorded by Clarence "Frogman" Henry, of Louisiana. It reached #4 on the charts on Feb. 26, 1961 on Argo Records, a subsidiary of Chess Records. It is found in Volume 3 of "American Rock & Roll" and has the complete music editions.
