I know that there are a number of people who read these threads who have made their own recordings. I'm curious if they pay any royalties when they record a "traditional" song - perhaps to the surving members of the source singers family, the publisher of whatever book they may have read, or the artist whose recording of the same song inspired them to record it as well. Do you also receive permission from those sources? If you find a song from the collection or archives of one these individuals or groups, do you pay them their due?
