The StarWars soundtrack was the first record I ever owned. Back when I was like 7 years old (ages ago), my parents bought me a record player and that soundtrack for my birthday. Ahhhh... memories. I somehow wound up getting the record for the Black Hole soundtrack as well, from a cereal box mail-in offer or something.
...oh, and I have to admit, in high school I bought the 45 for Ray Charles Jr's Ghostbusters theme song. (Don't tell anyone though, ok?)
