"produced arrangements to be sung in a light tenor to a polite piano accompaniment"
There's a lot of mileage to be got out of those songs still, starting from the collected words and the music and avoiding the trained voice and Sharp's piano parts, and avoiding other "revival" recorded interpretations too. And playing the game of "one song to the tune of another" when words and music were not collected together, which they often weren't.

"[the revival] has to a great extent governed what people mean by traditional music."
The revival IS (part of) the tradition, which is a history of perpetual change, innovation, reaction, preservation, backlash and disagreement. It's always been like that, and long may it continue to do so!
