Yes, PoppaGator, I was referring to the Tom Lehrer song. If you click on it in my earlier message, it takes you to a performance (not by TL) that's been put up on YouTube.

I don't think TL was parodying any particular song when he wrote it - he generally parodied genres, not particular songs (although he made an exception for Clementine).

My nomination of it as The Greatest Folk Love Song Ever was meant to be funny.
