There's not a lot out there on Bill Boyd. This is the best I could find, though I did not search exhaustively. Bluebird's 1975 release (AMX2-5503) of some of his thirties material is one of my favorite albums. Spanish Fandango, Under The Double Eagle, New Spanish Two Step, Strawberry Roan, Wahoo, Beaumont Rag, Going Back To My Texas Home, Steel Guitar Rag . . . they're all there.
