MGM owns the rights to the tunes; however, I did arrange this myself. Here's a Stargate-themed marching band show CONCEPT, complete with an arbitrary Donald solo and even a percussion feature! It includes the Stargate Overture, the Stargate SG-1 Theme and the SG-1 Closing, the Stargate Atlantis Theme and the Atlantis Closing, the Universe theme, and a couple other bits. Let me know what you think. Oh, and watch in HD as usual. Here's the forum thread for discussion. I'll be listing additional notes there as well. nerdonthestreet.com/forums/showthread.php?tid=44&pid=82#pid82
Note: I recently became aware that a band has already MADE a Stargate marching band show. However, that one was music from the movie only. This is from the entire franchise, and I consider that to be a large enough difference for it to be considered original.
