Charles, thanks for checking into it though!
Just the other day I had my VCR ready while I was watching tv. The commercial came on... I managed to get about the last 3/4 of it recorded. Of course, this was just for reference purposes that I could play to someone for help in the search. Too bad it was made only for the commercial. It would seem to me that it means it's totally proprietary and probably no one will ever get the song :(
But at least we tried.
