One time about 30 years ago now it must be I was at the The Old crown, Digbeth, and a young folksinger got up and gave us a rendition of The warwickshire RHA, which has the chorus

And when we get to france, me boys
the Kaiser he will say
Ach so! Mein Gott!
What a jolly fine lot!
are the Warwickshire RHA

This old guy suddenly stood up and proclaimed himself disgusted that a warwongering song should be sung in a folk club. he was howled down of course. I think somewhere along the line though, we must have lost a lot of the early peacenik/CND people who gave momentum to the folk revival in the early days. Almost without noticing it, we lost the wide focus that includes all reasonable and decent idealisms.
