I am inclined to copy. paste and save most of what Jim has just written. I think it sums things up pretty well.

But i will also say this again:
"The basic difference was the first Revival was it wasn't really a Revival at all. Lots of song collectors collected (?) took into custody loads of songs. They remained banged to rights until the Real Revival came along and set them free.

The Real Revival listened to 'source singers' and tried to understand how to sing the old songs. If MacColl et al sounded different between 1955 and 1985 it was because the were learning how to make the best of the songs. Nobody much had done it before and thousands and thousands did it in The Real Revival."

And we still do
