Bulmer & Sharpley collected the tunes and acknowledged the contributers. Most, but not all of the tunes were traditional, without the composer being known. Whether they were "acknowledged financially" or not, I don't know, and neither do you. I would assume that's between Bulmer and whoever contributed the tune. If someone collected a traditional tune from you to put into a collection, would you expect to be paid for it?
Or is this merely an excuse for another "bash Bulmer" thread ?
