Score one for Jolene the music sleuth
I found out what the song is! What song? This song from the Michelob Light commercial. Yay me!
If you too were wondering, "the original version was released on Giant Step Vinyl in 2001. The 'Bonita Fly' mix was just recently made, specifically for the Michelob Light Commercial. It will only be available commercially on the upcoming 'Turntables on the Hudson Volume 4' CD In Stores June 3rd", according to this site.
