I have never forgotten this song.I found it first at Glendermott Christian holiday centre at Anglesea on the Isle of Bute.The memories are faded now, it was in the early 80's, but it was a great holiday taking the ferry across from the mainland with my parents. I decided to try Googling it without much hope of success, but the tune is persistent, I had never forgotten it. At least I know now I didn't imagine it.
