Hold the phone... what about Jerry Silverman's Mel Bay songbook, KIDSONGS, 1990? Book, with tape, 48 songs, all folk stuff, not his own originals.If Mel Bay can use the term, you should be able to as well. Maybe you can Mel Bay to back up that the term is now "out loose" and anyone can use it. Their pockets are probably a lot deeper than yours! Or is Mel Bay part of Warner, and THE PROBLEM?
You don't want to bar Warner's use, right, just protect your own right to use it? If so it should not matter if you can prove you were first... just open the market now.
