Does anyone have a scan-able copy of the organ edition of Alan Gray's 'Book of Descants'? I had a battered photocopy for years but have not been able to locate it for at least 3 seasons. It's much rarer than I would have imagined--nothing available on Alibris, Abe, etc. Amazon claims to have a copy for $150, which I shan't be purchasing. Gray died in 1935, so it might not be out from under copyright.
