Okay, I got the last name, it's Justice Douglas.

The song, by the way, is sung to the tune of Humoresque by Dvorak. Same as "we went strolling through the park and goosed the statues in the dark."

The good Justice noticed a sign on the restroom door in the train ("Passengers will please refrain from using toilets while the train is standing in the station.") and noticed that it fit perfectly the melody of the Dvorak humoresque if you add three syllables to the end ("I love you.")

The rest (or at least part of it) he wrote himself, although many verses have glommed onto it in the ensuing years due to the "folk process."

Which is what Mudcat is all about, hey?
