A duo called Shamrocks in the Wind (Karol and John Diehnel from Tillamook, OR) performs I DON'T MIND IF I DO on their album "Frolick'n with Friends" (1997).

It looks as if the lyrics that Nerd posted above were copied from Shamrocks in the Wind's web site, but he missed the chorus which they show at the beginning of the song:

"Tour a lay, tour a lay, with my tour-a-li-your-a-li-your-a-li-a."

By the way, Shamrocks in the Wind don't say where they got the song, either.
