My then very young nieces had a good one a few years ago. The British humourous writer Richard Stilgoe had a song about a social studies teacher who insisted on everyone joining a steel band to help with "racial harmony" The little ears thought this to be a person called Rachel Carmody. She reminded me of one I had as a child in the song "Merrily danced the Quaker's wife," where I thought Merrily Dance was a person. I think that the two of them are probably well-meaning social workers, who wear droopy ethnic skirts, long hair, do not look really cheerful and need to be drawn by the British cartoonist Posy Simmonds. They also probably go to a folk club together, and specialise in singing, if no-one can stop them, rather sad, politically correct lyrics about mis-treated women, accompanying themselves with an autoharp which they can only strum. They do not drink, and never talk to the other members if they can help it.
