Surprised at how few (virtually no) source singers suggested here.

I touched upon this in an earlier post, but albums of the old traditional singers (why do I not like the term source singer?) operate more as DOCUMENT than PRODUCT, and PRODUCT is pretty much what's under discussion here. That said, one of my personal treasures is the Topic John MacDonald LP The Singing Molecatcher of Morayshire. There is a rumour that he misunderstood the copyright law and after the LP was released never sang any of the songs on it again. True? Who knows...
