Phil's Rambling Rants
You sing lots of stuff I've never heard anywhere else. You might think of it as old material everyone knows by famous people who made great studio recordings you can't hope to match, but if it was written 20 years ago by someone way out on the east or west coast, and that recording is out of print, and no one else has sung it publicly in the Milwaukee/Chicago/Champaign area in a decade, well, it isn't really a problem if it isn't actually original and new, is it? It might be new for a good fraction of the audience. Anyway, you are certainly a strong enough performer that you don't have to try to compensate for a marginal performance with novelty.
