Thanks, Parkin. I did manage to work out his dates, I think, from the publicity about Colin Bacon's new book. Incidentally, thanks also to the forum member who directed us to the author interview by that Nottingham online magazine. It was much more interesting than the article in 'The Chap' and gave a real sense of what MacKerrell (and Robinson, for that matter) was/is like.
Given that this year is the quarter-century anniversary of the film, I'm sure there'll be other new books and more publicity. This Forum provides a real service in letting us know what's out there, especially for IT retards like me who can only just switch a computer on. What's a mojo? (Yes, I know: "Keep up, grandpa.")
