"(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".[1] 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.[2]

The song was made popular again after its use in a 1993 UK television commercial for the Fiat Cinquecento,[3] appearances in the 1994 film Forrest Gump, the 1999 film Mickey Blue Eyes, and a 2019 commercial for Expedia and its ability to provide dog-friendly hotel accommodations.[4]
