Alba regularly repeats some programmes, just have to keep an eye open for them!
Robyn is one of the Glasgow Conservatoire (formerly RSAMD) Traditional Music graduates, qualified a few years ago. She used to attend Glasgow Ballad Workshop (now Glasgow Ballad Workshop 2020 - facebook page) as did a number of students being tutored by Gordeanna McCulloch and Anne Neilson.
I agree Robyn is an excellent example of how traditional and Scottish songs should be delivered - clearly, simply and from the heart!
(I really dislike the 'performers' whose egos are more important than the message, the history of the song.... )
