Well - that one is NEWS to me. I stand corrected. I had always heard that the "birthday song" (afraid to say the name, now !) was public domain. Either way - I believe that the only way to enforce a royalty should be in a profit situation. No one can tell you what to hum, or whistle or sing on your own time. It's only when profit enters the picture that requires more serious attention. This is all sounding too much like poitics to me. I stay in show biz because I can't STAND politics. I hate to think about how the "other half" lives .... I just wanna sing.
