Mick Bracken's song looks to me like a version of the Scottish song "Happy Friendship" which Willy Scott, the Scots shepherd, used to sing wonderfully well. We thank you for that text, Mick! Caroline and I have a truncated version which I learned from Paul Clayton, who had it from his family (grandfather?) in New Bedford, Massachusetts. In fact, we sang it at BBC's party for Bill Sables last weekend.
For anniversaries, we often sing Bruce (Utah) Phillips' "HYMN SONG." Seems appropriate, with words like:
I believe if I lived my life again
I'd still be here with you.
