Mike, re discography
I can't imagine anyone buying FSE who hasn't already got a copy of New Penguin which has a perfectly good discography.

Despite the length of this weighty tome in almost every chapter Steve goes to great pains to stress that evidence is very thin for previous centuries as you would expect with a subject that deals with the history of the common people. However he has obviously searched diligently for what evidence does exist and personally I can't see this amount of evidence ever being greatly added to or contradicted.

The evidence is clearly stated and leaves us largely to draw our own conclusions.

Re Bert Lloyd, I'm absolutely certain Steve wasn't motivated to write his book by Bert's fairy tales. There can't be many people left on the scene who don't take anything Bert wrote with a pinch of salt. This is not Bert bashing time. He was wonderfully gifted and left us a wealth of well-crafted material.
