Seeking one or more copies of Earl George’s “Aaron Stark”

The choral octavo “Aaron Stark” is a wonderful work by Earl George, which I have conducted in the past. Inexplicably I cannot find my personal score for it, nor can I find any multiple copies in our library. Mystifying, but I’m a creek at present, because it is permanently out of print. All I really would need to obtain is a single (reasonably clean) copy from which I could make copies (after receiving publisher permission, of course). If someone would prefer only to rent me multiple copies, I would accept that offer as well. Desperate!
Thank you.
