I have found the most complete, though concise explanation of dutch roll from this site:

I found this easier to picture than either Davies' or the Naval Aviators explanations. And of course, dutch roll has nothing to do with stall, though I have spoken to a colleague of mine who used the Bristow explanation in his interview and got a grilling from it!
I have also spent a few hours pulling hair out over Bristow's errors, and have a few more errors to add, but it'll have to wait until after my interview - too busy studying now!
