Well: We're paid to entertain and to me, there is nothing more disheartening than the look on some-one's face when they ask for a song like Danny Boy and don't get it.
It's also about demographics though. Seems my audience is getting older every day. Same people I sang to 25 years ago but some how, they've aged.
Now... If somebody wants to ban John McDermott, I'm up for it!
