... then it's clear that no progress will be made, mistakes are ignored and repeated. We hack through the songs and get lucky occasionally, but often it is a somewhat embarrassing trainwreck. I guess it's common to have different expectations arise... some care, some don't. I'm no perfectionist, but I like at least some desire to improve, and present myself with integrity. Retired Grandpa bands... is that my sad future?
Ouch. As long as the hang is OK then my opinion would be "a bad granddad band is better than no band". I'd keep an eye out for something else and move on at the first opportunity.
However I acknowledge that not everyone lives in a densely populated area as I do, so there might be no other opportunities.
Condolences, regardless.
