"He may have 'messed about with songs', which didn't please all the academics but, to my ear anyway, he always stayed faithful to the reason they were first created.   
Jim Carroll"
Iagree Jim
Brian, Bob Roberts did write books for example BREEZE FOR A BARGEMAN, and i am sure that somewhere i read that he wrote the song" SWELL MY NETS FULL", and he probably wrote The Oily Rigs monologue, he did not claim to be a scholar [true] but he was clearly capable of writing good stories, which brought me to the conclusion that he wrote part of a most unusual and unique version of while gamekeepers lie sleeping., which appears not to have been collected by anyone, which is suspicious.
what is this seven verse version of bob coppers? does it bear any relationship to bob roberts[i doubt it] if its the same as tom willetts version, storywise willetts version may have seven verses but not much of a story, and no resemblance to Roberts' version
