A friend of mine divides mistakes made by musicians in performance into two categories:
1) Cows on the track
A few bumps but the train kept rolling.
2) Train wrecks
Train came to a grinding halt, derailed.
Like Jerry, I'm likely to forget any mistakes heard when I'm in the audience. I'm not a critic; I'm a celebrant.
As a performer part of my job is to press on beyond the mistakes I'm bound to make and deliver entertainment to the folks. I can do that best if I laugh at my mistakes (inwardly) and practice that bit when I get home. Even if a "Train Wreck" occurs, there's no loss of life!
Jerry, if you're still out there I'm just knocked out by your tape and I'll be in touch. Your songs connect directly to the heart. I've been slow to respond, but I'll make up for that. Keep writing! Art Thieme and Rick Fielding, et al, weren't jiving, you got the stuff.
regards, Chance
