Also if you are at a festival look out for Shan Cowan (of Martin Graebe and Shan Cowan) Frankie Armstrong, and Chris Coe all of whom do workshops.

I booked Ewan and Peggy for a concert and they were the first folk singers (in fact any singers) that I heard doing vocal exercises before performance. I believe Ewan used to sing "Highland Muster Roll" as his first song - to test his voice angainst the acoustics.
