when in Edinburgh go to the tourist info centre and pick up a copy of the Whats On leaflet. It gives details of all music in the city for about a month. Sandy Bells is worth a visit as is The Wee Folk Club in the Royal Oak. The may not be Traditional music but it will be fun. Watch ot for a band called Tarneybackle. They are excellent and the have a web site for furtherinfo. The hail from Perth which is only an hours drive if that.
