MY apologies Matt Keen.
Jim,you say that the early revival was more willing to share.
Martin Carthys dispute with Paul Simon over his arrangement[and it was a sophisticated guitar arrangement],occurred either early or mid sixties surely that classifies as early revival,it was over 40 years ago.
IF you are right,there may be an explanation for that perhaps there are more composers[writing in traditional style,and contemporary style] these days,and more people needing to pay their mortgages.
The early revival would have featured teenagers who perhaps were beatniks[see WizzJones youtube 1961,and Newquay]. Sadly Peoples aspirations change,when they get to be sixty,they are no longer happy living in a tent,and want to be able to pay the next electricity bill ,that means if thay are a composer songwriter ,they need every penny from royalties,because they dont earn much ,often less than the minimium wage from the folk scene,
Most professionals could earn much more in another field,but their love of the music has kept them available for the folk scene.
