Point I was making was that they were regulars at the Chorlton ceilidh and might become the next layer of players if you were to start up a new beginners session and make it known.

A new beginners' session... not sure there are enough Beechpeople with enough free evenings. But it's an interesting idea. Personally I'm not going to the formerly-beginners' tune session much at the moment; I could probably do with a remedial laggers-behind session. Or I could take the 'tina - I'm certainly a beginner on that... Interesting one.
