Jerry, the other day, for some reason, when I posted my recent message on this thread, I had the scene from Blazing Saddles flash in my memory
quote:

    Bart: [Crooning, with fellow railworkers providing backing vocals] I get no kick, from champagne... Mere alcohol doesn't thrill me at all...[the bullying supervisors look immensely confused] so why then should it be true?... that I get a belt - outta you... Some get a kick from coca-yeai-yeaiiiinnnneee...
    Lyle: Hold it! Hold it! What the hell is that shit?! I meant a song! A real song! Like [singing] "Swing low, sweet chariot"...
    [The railworkers mumble to each other in mock confusion]

I thought of all the times songs of all kinds are mixed together in the groups of people I know, the freedom to sing just in the pure love of a song. It seems weird to me that there is so much categorizing and rules of what is allowable... or not.
