Here's a cool oddity that I recently discovered: a sound effects LP from Walt Disney Studios/Disneyland Records featuring laser blasts, explosions, spaceship engines, etc. From the appearance of the Black Hole robots on the cover art, I presume this came out around the time of that movie, but the rest of the album artwork is generic space opera stuff.
If you're interested, you can download the album here or here.
