Thanks for the input. You're all correct of course, it is Long Harvest. And it must have been a compilation that I made myself, because I own a set. (In fact, I believe Dick used my pdfs of the notes for the reissue).

I was thinking that it couldn't be, because I don't think of 'I'm a Rover' as Child. But as soon as I checked... - they classified it as a version of 'The Grey Cock'. It's a very nice selection :-)
