I do not think we are mistaken. Michael and I were good friends in the rather turbulent period from 1978 onwards. In fact when I left the UK in March, to come here, I stored a large number of books in Michael's garage. (I think this was in Oakengates, but I'm not sure.) This was when he and Pat were still together.
But I know that he did not remain long in the BAF afterwards and so I'm sure 1980 is the right date for the start of his organization, under Tamura Shihan's direction.
We met once more, well after 1980, when Mike came to visit me at my parent's home in Nottinghamshire. We had lunch in a restaurant near by.
Anyway, Darren, please give him my best wishes when you next meeting--and I wonder what happened to the books.
maybe Peter G. and I are mistaken.
Anyway please give Mike my regards.
