Good point Les. I never considered that. Being chucked into an academic mess full of persons with loads of brains and no common sense is something that happened to me in the 1980's when I was song collecting. I ended up throwing my toys out of my pram and sulking for a decade or so. You would be amazed at the venom spat at me. I can sort of forgive Bert for cutting a few corners. {I think} Something about the road to hell and good intentions springs to mind.
