Some time ago one of my friends was involved in a function at Rydal Hall in Cumbria (the north-west corner of England). He was shown an ornate wooden chest given to the Barnard family in the 16th century by the Musgraves on the occasion of a wedding in the Barnard family, in an attempt to end the long-running feud between them, said to have started in the 12th century.
This prompted him to sing the song. Having started, it occurred to him that there were several clergymen and numerous children listening, and perhaps it was not the most appropriate song for the audience. However, having started, he felt compelled to finish it, afer which there was a deathly silence until a small girl remarked "so it was quite like East Enders really, wasn't it"?
(East Enders is a soap opera on British TV.)
