Many thanks, both. I'm building up quite a store of useful information now, and also feel greatly cheered after attending a friendly session in Brixham the other night. I'm in Stoke Gabriel, near Totnes, so I have to get used to driving in these narrow single-track lanes, but I'm getting the hang of it. The Harberton Folk and Flaxey Green websites are very useful for this area too.
Thanks again for the info.
