Thank you both. I will probably stick now with the set list that I have already written. However after the event I will review the material and see if I can develop it into a form suitable for offering to storytelling clubs or festivals. I will write new poems specifically to go with the storytelling material. I will sit down with the folk song material and learn by heart songs like Tam Lin. I would extend the material for a longer spot. I have just contacted a fellow poet over a local writers' group that would give me support. I'd considered The Lambton Worm but am not sure how credible I would sound with a voice that I've been told sounds posh! I love the song though so will probably learn it; Lambton is one of the screen names I use on the Internet.
