He put that to music way before 1978, it was probably his earliest marriage of poetry and music. I remember riding the Fauntleroy ferry in Seattle over to Vashon Island prior to 1965. We were singing it back then in the family station wagon. Probably at the top of our lungs.

It was on a similar ferry ride when my sister, four years younger, spotted a deckhand working the lines and asked if he was a "dirty little cabin boy." Hilarity ensued!
