Interesting questions about Lomax. Sandy Paton knew him and might have some thoughts on this. But a fascinating read is the story of Skip James. I'm sorry, it's late and I've forgotten the title and author (Steven Calt?) I'll check it out tomorrow if no one does it first. One of the points made however, was that none of the blues rediscovery guys had a clue just how small the market was at the time for their music. They figured that the enthusiasm of the collectors represented thousands of new potential fans (and album sales) when in fact it was more like a few hundred. Probably same thing with a lot of the folks Lomax collected, so they made diddly. I doubt if Lomax got rich collecting music. Whether he got rich in other ways, I don't know.
