Pom Pax, my memory o f that is a bit dim. We had Roger McCrann for 41 Course until 16/18 of us had an administrative recourse. The chop rate was too low and 1ANS could not cope. Roger was a wild batchelor and many was the mess fine for broken glass etc as he led us in hectic sessions late at night. Then we had George Kaye, married and an altogether more stable character.
Though I remember their name, and one of the two at 1ANS I don't recall using their first names. I think it was probably a hang over from school days as most of us were literally just out of school. I think Mac Browse and Harry Sime were older.
Only at BCBS did we call Larry Robinson, Larry, but that because we had 3rd and 4th tourists in the course.
