There is a song used in several Universal Studios DVD commercials that I would love to find the name of, if it exists outside of the commercial. There are no words to it, it starts off with some percussion, and it can be found on commercials on the DVDs for The Mummy Returns. There is a version of it that has an electric/air guitar prominent, and another that doesn't. I have heard it credited to The Blue Man Group and to John Pratt; some people insist it is a full song called 'Ecosystem' and others insist it is just a short piece of music created for Universal Studio use. I don't know who to believe, and what's more, I can't find it to purchase it on itunes or other mp3 sites. Can someone please tell me what the story is behind the song and if and where I can get it for my ipod? Thank you very much.
