"What 'flavour' of folk music is prominent currently in England?"

I don't detect any "flavour of the month" emphasis at all. Last night it was a typical mixture of stuff such as some Rob Johnson slide blues, through Fats Waller's "Black & Blue", Gordon Lightfoot's "Minstrel of the Dawn", John Denver's "Colorado Rocky Mountain High" etc to our guest singer/songwriter Anthony John Clarke. Tomorrow it's off across town to see Flossie Malavialle, and then on Saturday it's over to see Jez Lowe plus a variety of floor spots. All within a 5 mile radius. All thriving clubs very well attended and with great atmospheres. Wonderful stuff

Who said folk clubs were in decline!!!!!!!!!
