looking for an early 1980's demo for C64

this was well before the demo scene. At least, I think it was a demo,
it might have been an intro to game. I honestly don't remember.
Anyway, I am pretty sure it was called "Odyssey" or at least it had
big words saying that. Then it had some kind of flying saucer come in
on the screen and it was playing a tune that highly reminded me of the
eurythmics song "sweet dreams."

Sorry I can't give any more detail. I just started thinking about
this recently, but this was one of the first things I ever saw on my
C64 back around 1983 - 1984 era. I was just a little kid. Don't know
why I am just now remembering this. But if anyone has any
suggestions on what this was called or where I could download it, I'd
like to see it again.
