I have close to perfect pitch, and, if I am hired to play a house piano that is even slightly out, it literally makes me sick.
Dave, if you ever were able to come back, I'd clear the schedule for a week. We just touched the surface of the instruments last time. I'd take the week to visit all the places in town I played years ago...haven't been in some of them for years. We'd visit Louisville, where I'm now involved in a 2nd guitar club in a school with disadvantaged kids.
Teaching is such a noble thing to do, and teaching music is even better.
And old "heart on the sleeve" Dave is the perfect guy to do it!
Best regards, all,
