Jon Boden tells a funny story about Jinky Wells: how a collector saw him playing for the morris and in the pub asked to inspect Jinky's fiddle. He looked it over and strummed the strings, pulled a bit of a face and proceeded tuned it. He handed it back to Jinky and said "Here you are Mr. Wells, I've tuned it up for you. Whereupon Jinky took the fiddle, put it under his chin and began to play Vivaldi's Spring from the Four Seasons. The collectors jaw dropped with surprise at Jinky's skillful playing. Jinky then retuned the fiddle to where it had been.

Obvioulsly, JB does it better with suitable illustration on his fiddle.
