50th Music

Does anybody know where the music used in the kickoff celebration on May 5, 2005 for the 50th was from? Was it specially written or is it a soundtrack? At least one clip of the same score was used in the commercials for the 50th. Any info you can provide is appreciated. Thanks,


I think it was for the event.. I know it was played live on May 5th and when the conductor was introduced I think they said they made it for the event.
