There used to be a housemaster called Priestwood, I think, at a prep school (UK meaning) near Harrow called Orley Farm School who had a collection and occasionally used to let the kids listen. It should be in the book!

Oh, and Dave Bryant, who calls himself the Toto GObbi of the Balls Pond Road and advertises in one of the EFDSS magazines to get gigs also knows at least two of the songs mentioned.

Happy hunting.
