I'm not sure about a TMS mp3, but...
The song in question is from a Broadway musical called "The Pajama Game". If you really like that song, you might wanna check out the soundtrack from that musical. I know for a fact that this past Broadway season, they did a revival of "The Pajama Game". What I'm *not* sure about is if the revival has a soundtrack. If you can't find that, then try either the original soundtrack or the movie soundtrack. Good luck!
