If you wander the same regions of the Internet I do, you've probably seen the Space Stallions "trailer."
It's popularly called the '80-est cartoon that does not in fact exist. (It has also been called one of the gayest things ever, and that's not meant in the pejorative sense.)
The most obvious comparison would be to the Silverhawks intro, which has a lot of imagery in common.
There's also parallels to the Thundercats opening (I'd have embedded that, but apparently that's not allowed anywhere on YouTube-and I checked at least four videos).
Then, of course, there's the fact that the leader plays a keyswordtar (keyboard/sword/guitar, or rather, a sword turned into a keytar) while standing on the head of a spaceship shaped like a horse, which is the main thing that gets a lot of people chortling and pointing to the single craziest thing in it.
