ONLY a few songs had the kind of impact, Coat of Many Colours, the October, 1971 song by Dolly Paton, had on me. It talked about a poor kid whose parents could not afford  to buy her a  coat “way down in the fall’ and how her mother made her  a coat from a box of rags “sewing every piece with love” while telling her the Biblical coat of many colours Joseph wore. She sang that “Although we had no money, I was rich as I could be.”
