I intentionally said "any".

I also intentionally said "folk".

There was quite a lot of sort of god-ish stuff and gospel revivalism in the USA in the 60s, but apart from the gospel side it was mostly not within the 1954/5 definition of folk (see other threads).

Anyone got any other ideas what connection punkfolkrocker could be talking about? He's too young for the crypt under St Martins, surely?
