The folk music scene, on both sides of the pond, has been fragmenting. In the UK, singers (generally) don't seem to play instruments; instrumentalists (with obvious exceptions) don't sing and dancers don't talk to anyone but other dabcers.

In the US, what was once "folk" has split oiff into Blues, Old-Timey, Bluegrass, Gospel,Country, Irish, Celtoid and a flock of oher specialties which seldom seem to inteact. Back when bluegrass was new (early 1950s), it was viewed as a commercial form of music that was being forced upon the folk scene--I remember the schism between "bluegrassers" and "Greensleevers".

Onct upon a time, I remember dancers who sang and played, and all the permutations possible. Prolly never no more.
