Thanks, but it's certainly not mine. Down at the bottom, you may have noticed it's attributed to Jon Anderson/Steve Howe/Rick Wakeman, and it's a song titled "Arriving UFO" on Yes's "Tormato" album. Actually, I think that's one of their more "overlooked" albums, with lots of really good songs. A great concert tour as well.

The symbolism in the song would make for the basis of a science fiction novel.
