Cookie vanished. Never mind!
I've seen Anna and Emily perform and know something of their pedigrees and whilst they are very good at what they do.........
Strangely, though I've seen Sam in other contexts, I've not actually seen him perform music. However I know his relatively brief pedigree in folk music is phenomenal. I asked him to come and give the final presentation at a seminar in York on folk music in education. Most of the audience were older hardened folkies and music leaders. He blew us all away. His commitment, enthusiasm, energy, eloquence, intelligence make him my first choice.
Anyone know what the criteria are?
