PLEASE HELP! What is this soundtrack??
 

Hi guys. Great forum. Need your help!!

I had an old (believe it or not) reel-to-reel tape of this anime soundtrack in about 1982 and don't know what it's from (I managed to lose the jacket with the japanese characters on it, but would probably recognize them if I saw them).

A small sample is located at this link: **mystery soundtrack**

I'd love your help to know what this soundtrack is from!!

Thanks.
