A story from Martin Carthy: Doing a tour of the Republic of Ireland by public transport [only he could do this and tell the tale] MC fell into a session on a Sunday afternoon with an octogenerian and arthritic whistle player. On complimenting the old feller on his playing and attitude MC was told,
"It's easy, you have to love the music. If you don't love the music you won't practice and if you don't practice you won't be any bloody good. "
I've used this for years with students, so thanks Martin...says it all really.
