Twas ever so.Just one more thing and as is said elsewhere in this thread, it is a huge difference when you use copyrighted music as an amateur or as a professional. Amateurs borrow, professionals steal.
In the folk world, performers would take a traditional song, record it and then publish a book which claimed copyright of the words and melody. Someone composed (should that read improvised?) it in the first place but it had become public domain. Quite what the lawyers would make of this, besides loads of money, I'm not sure. In common and I am very common, with most folkies at the time, thought it was a giant rip off.
