in 1962 whilst on a holiday to ireland wih my pal and his family we visited either friends or relations of his father in a suburb of dublin. the lady of the house said her husband,a postman,had written the song forty shades of green. years later i read that johnny cash had written it. then quite recently i saw a video in which during a concert in dublin jc introduced the song as having been written by him and a female member of the audience shouted "oh no you didnt" the plot thickens!
