At the end of the Farrelly brother's movie, Stuck On You, Walt (played by Greg Kinnear) sings a song during the Bonnie and Clyde musical. I have searched the internet, and cannot find an answer. Anyone know the name/original composer of the song?
Thanks!

It is a version of "Summertime" which I think was originally composed by Gershwin in Porgy and Bess. It has been covered and rearranged by tons of artists. I think I read somewhere that there are almost 3000 known versions of the song.
