"so this guy just stopped playing and somewhat apologetically said to the audience, "Sorry, but we tune because we care""

Once started playing the accordion at my turn - you might notice that the left hand has all these different rows (al the other (wrong) keys)... well it's not hard, especially if a bit nervous at the first appearance at a new place to grab the wrong row!...

I thought it sounded a bit 'off', so stopped and said "well, I stuffed that up didn't I? I'll just start again and push the right buttons this time!"

The looks on people's faces was priceless. Some nearly even fell off their chairs!

And if you haven't heard me in full flight on a good night, don't display the true nature of your soul by making negative comments!

:-P
