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.
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.
