Thanks Marje. I was thinking of making that one of the variations every second bar as the tune lends itself to that. The players in the past have been a great mix, from those who have never played in public to those who play regularly, but they do tend to play from the dots rather than by ear.
I am thinking a workshop is a bit like a cookery book. If you pick up one good recepe then its worth it.
