Eavesdropping on the critics

Ewan McColl's Critics Group is the stuff of legend. McColl responded to the folk revival of the 1950s and 60s by taking the music seriously, and trying to ensure that people did it right - whatever "right" might be. This much I knew, but I didn't know that Charles Parker - yes, the Radio Ballads' Charles Parker - was a member. And he kept the tape recorder running.
