Thanks for the link to the Gainer material. New to me, and there's an interesting version of Child 1, that I'd not heard before, there too.

The 'Murdered Sister' he sings doesn't appear to be in Bronson, but looks like a rare instance of a 'Bow Down' variant including the magic fiddle. Do we know whether Gainer performed the songs exactly as collected, or was he prone to 'improving' them?
