No, Phil, you do not have to tune... I have two autoharps and you can take your pick of either one, whether it is in tune or not. :~)
I do not mind donating whatever talent I may have-- I do resent the assumption that my donating it can be assumed or assigned. I volunteer in MY church. Anyone else (especially other churches) had better plan on paying for professional services.
I had agreed to do the camp as a volunteer. I was donating the week of playing and the prep time, not the time it has taken to chase down the arrangements to go do it. I had not agreed to be treated unprofessionally by people who (I thought) were being paid to be professional...
I can't believe how mad I still am, this late in the day.
