There are whole books on Bert's creativity/scholarship, Dick, and currently the person we all know who is working on the many examples is Brian Peters. I can give you examples from my own experience but I'd only be repeating what I've previously put on Mudcat. Have a look back through the threads on Bert and you'll find plenty of examples.

By the way, Dick, and this is not being patronising, there are 2 really useful posts you have put up recently which I don't think anyone would argue with.

Once again, and we must have said this a thousand times, all of us have enormous respect for what Bert and Ewan contributed. We just wish they hadn't confused their scholarship so much with their creativity. For a long time Bert was seen on the folk scene as one of the top scholars when it came to the history of the songs so it's only right that today's scholars correct any 'creativity' when it clashes with the facts.

Once again, everyone who has contributed here is as much a singer and lover of the music as you are. It is possible to sing and study though perhaps not at the same time.
