That got me to think of a couple other favorites, who I've mentioned here a few times, the British team of Michael Flanders and Donald Swann, who had a couple of very successful musical revues on London's West End and Broadway -- At the Drop of a Hat and its follow-up, At the Drop of Another Hat (which also got broadcast on CBS as a TV special).
I mention this because, of the many wonderful parts of the initial show, which played on Broadway in 1959, there is a seven-minute erudite and funny monologue by Michael Flanders on the history behind the song "Greensleeves." (He's the bearded one below.) There are none of the pair's comic musical numbers here, just the background music of the song in question, played by Donald Swann. But as great as their songs are, Flanders' monologues -- including one of being a bored tennis umpire -- are as much a joy.
