At a Transylvania college choir rehearsal, the guy we all called Sugar Bear began his solo of "My Old Kentucky Home".
"The Sun shines bright on my old Kentucky Home"
"'Tis summer the darkies....Young Folks! are gay."

Here in Pittsburgh we revere Stephen Collins Foster. We sing his songs, and name things after him. But we alter his lyrics when he uses improper terms for people of African descent. Those words may have been acceptable in Foster's time, but they are offensive now.
