I have just remembered a colleague of mine,from my time in the aircraft-carrier HMS EAGLE in the 1960s. He was an Engine Room Artificer, and a fine banjo-player ( he had a Vega 'white lady', I recall ).Anyway, his ambition was to leave the Navy, ( What is it about ERA s that make them want to leave,-like ERA Tawney,C. ??) and become a teacher !! I often think of him, & hope that he lived his dream---He came from Suffolk, & his name was Pete Wimpenny.
