For me if you can't get excited about performing in front of a crowd you're in the wrong business and I've been doing it since 1964.
You nailed it Bob. That's me right now. It's just another night of music. 1000 in the room or 25, it's all the same to me. As long as my check doesn't bounce.
Now, to do a night of MY music, that would have my juices moving a little faster, but telling somebody else's story means zero to me. If I was to perform my song "I Hope Somebody Cries", which was posted here a few years ago, that's a soul baring story about how my shining personality has left me with a grand total of 4-5 people I can call friend, and that song died the slow death of silence that you risk with originals, that would hurt my soul. But to go out and play copy music, I don't care. That's why I don't gig other than with this tribute band (which is just another way of saying copy band).
