Mostly for the love of song, the music. If I wanted to make money at it around here, I'd have to start singing "Stand By Your Man" and others "dainsible" songs.
When we do get paid, I turn over my share to the local Celtic Festival group -- so they can get other musicians to come to Amarillo! It's ever so much more fun, knowing I can play and sing whatever strikes my fancy, instead of worrying about whether or not the two-steppers are happy.
But I'll tell the truth: I'd rather trade songs around a campfire than Perform, any day. Even those magic nights when everyone is with us -- nah, I'd still rather be on the other side of the microphone, singing along and letting someone else think of what song to do next, what witticisms and general philosophy to share while re-tuning. I guess I do it 'cause we're the only Irish/Scottish/general folk music show in town.
