I didn't mean John Doonan's Irish music. He is on recordings with well known names of NE English music playing English (and probably Scottish) tunes. We hear an uncommon instrument being played in a style that borrows heavily from Ireland.

On another tack how about Scan Tester's repertoire? Quite a bit of that was from outside England. He was an English folk artist and his music was part of the the 'folk art of England' - in my book even when he was playing 'Edelweiss' at a festival session in the 60s. (I'll back off on that line before we get to folk clubs and Buddy Holly)

VWML did well on funding over the archive material, and pushing 'English Tradition' to the fore over that made sense. But what the folk do in clubs and pubs and what they listen to at concerts is wider than that but 'of England'
