"'''(I Don't Know Why) But I Do'''" is an R&B song written by Paul Gayten and Bobby Charles (as Robert Guidry), and performed by Clarence "Frogman" Henry.

==Original version== It was Henry's biggest U.S. hit, reaching No. 4 in early 1961. The B-side on the single release was "Just My Baby and Me".

On its initial release in December 1960, the U.S. release on the Argo record label was titled "I Don't Know Why". However, about ten weeks later, Argo announced that due to confusion arising from the song being mistaken for the 1931 song called "I Don't Know Why (I Just Do)", they changed the name of this song to "But I Do".<ref>{{cite web|url=https://books.google.com/books?id=TCIEAAAAMBAJ&q=5378&pg=PA40|title=Billboard March 13, 1961|page=40|website=Books.google.com|date=13 March 1961}}</ref> The UK release on the Pye label and the Australian release on the Coronet label were both titled "But I Do". The UK version spent 19 weeks in the charts and peaked at No. 3 in the first week of May 1961.<ref name="auto">Rice T, Rice J, Read M & Gambaccini P, Guinness Book of Hits of the 60s.
