the warrior, or the warriors? If the latter, no, you CAN get it, try HMV or virgin. That's where I got mine from. Trust me, it's not as good when you get it home.
I reckon you could still pick one up at a record fair or on ebay. It was released on A&M records in 1979 (cat no AMLH64761). I have a copy on vinyl if you wanna make a sensible offer??
hold out hope friend. I worked at a cinema during the showing of the warrior, and they came to us with a 'sale or return' deal with their soundtrack. We returned all of them, so they should still have plenty.
