You said McColl became "exceedingly rich" from "First Time.." Jim merely pointed out that he did alright out of it, and was "well-off" he was not what most people would consider "exceedingly rich". Jim thought your claim, which seems to have been based on supposition rather than personal knowledge, smacked of sour grapes, and I rather agree. McColl gets a lot of posthumous flak, and Jim understandably feels the need to protect his friend's legacy and to correct what he perceives to be inaccuracies.

McColl was fortunate to write one song which did particularly well commercially, and quite rightly benefited from it. He wrote a great many more which have endured but which I suspect brought in rather less financial reward. I'm not sure why either points are relevant to this thread.
