Speaking of song parodies, I heard on the late Clyde Gilmour's show on CBC an English group from the 1960's called The Mastersingers. (They were teachers) The song was sung like classical sacred music, but the words were a weather report for the UK. Apparently they specialized in this sort of parody. I'd love to find anything by them on CD, although I think Gilmour said he was playing an old 45 from his enormous record collection.(All the music on the show came from his personal collection of tens of thousands of 78's, LP's, 45's, CD's, and what have you.)
