I stated that your use of the phrase “public domain” is nonsense. Nothing you posted contradicts that.
Semantics. Commercially disclosed and public domain appear to be the same thing to me. Perhaps not. The real question is if Young can dictate who can play his music publicly. I don’t think he can - as long as his royalties are paid. If you have a solid legal basis that refutes that, then please let us know so that we don’t waste any more time debating this. Personally, I could care less what Neil Young does. I hope he has a wonderful life in his remaining years.
