I should make it clear to the forum that suggestions do not have to be PM's they can be posted in the open. Depending on budget my immediate suggestions are: -

Wasps in the Woodshed (support slot)
Ian Bruce
Nuada
John Kirkpatrick and friends
Bluehorses
Iron Horse (are they still together)?
Peatbog Faeries
Davey Rumsey (support, preferably without his electric band)
Sussed (they have now changed their name to something else: as support - very contemporary)

Hmm, not a lot of English in there, I must give it more thought. I suppose Young Coppers are out of the question?
