Really enjoyed reading your anecdotes Don. It's funny, since I've been singing solo and playing fingerstyle (and worrying incessantly about screwing up!) I've become a much more acute and sensitive listener. I've noticed "mistakes" on albums by musicians who are total virtuosos (Bert Jansch and Davy Graham, to name two). Once or twice while watching Jools Holland (a live UK music show) I've noticed the occasional fluffed chord or off-drum fill or whatever.

It makes you realized that ultimately, when you think you are making a horrendous glaring mistake that everyone is judging you on, the sad truth is that nobody other than boring music nerds will even have noticed!
