I assure you, Nerd, Jim Larkin didnt know anything about Paul and Linda Adams (or much about the folk revival for that matter!). And in point of fact the tune he sang Canny Cumberland to was not the one that Paul and Linda recorded. Jim's was virtually the same tune that Kidson noted in Kirby Lonsdale 60 years before(and also the one recorded by the legendary Greg Stephens on a Fellside record produced by Paul Adams!).
