Well, as far as I'm concerned, "Starry Starry Night" is right up there with "McArthur Park" for let's all slit our wrists and have a pity party for the survivors.... Thank you Don McLean!
The Unicors Song belongs to a different but closely related group of songs, I think. The "Sing it again and I'll kill you" family of cute lyrics and hypnotic tunes. Another of these is "Little Gomez" by Eric Bogle.
