There is a wonderfully hilarious Scottish parody of "Frankie and Johnny", written at Rutherglen High school a good few years ago, and entitled "Mary and Bothwell" (about Mary Queen of Scots): it's sung a lot this side of the Border, and includes the death of Rizzio.
Don't have the words in an easily pasteable form, but I'll post them some time.
In the meantime, hello Kitty and Derek and thanks for your lovely singing at Sidmouth.
