If you meant the Sharp quote Brian it's in Vic Gammon's paper "‘Many Useful Lessons’, Cecil Sharp, Education and the Folk Dance Revival, 1899-1924". Downloadable from a link in his academic profile.

A couple of things struck me about Harker when reading Vic Gammon's paper. One is that if he Harker had really wanted to put the boot into Sharp then the dance side of things would be a better target.

The other is business of Harker being 'snide'. I think he is 'snide' but to be fair the way he describes himself as a middle-class traitor includes an element of humour and some of the other comments may be meant to be(at least to his comrades). I would find "The Sharp mythology, well on the go in his lifetime and oft repeated since..." irritating from Harker, but in fact it's Gammon in a very clear, measured essay, so it just raised a smile.
