Ewan MacColl quoted by Jim Carroll -
1.       It is necessary to rescue a large number of young people, all of whom have the right instincts, from those influences that have appeared on the folk scene during the past two or three years; influences that are doing their best to debase the meaning of folk song. The only notes that some people care about are the banknotes.

Intriguing. It sounds as if the rot had set in 45 years ago.
