Have you seen the ghost of Tom?
Long white bones with the flesh all gone
Ooh-ooh-ooh-oooh, poor old Tom
Wouldn't it be chilly with no skin on!
Googling on it proves that it's widely known, but no one seems to know who wrote it. So, is this a song that just a few schools learned? Or nearly all kids in the U.S.? Or all over the world? Now I'm curious:
Do you know this song?
Yes, I do know it (though perhaps the lyrics were a bit different)
Sounds vaguely familiar
Nope, don't have any idea what you're talking about
ETA: Here: I found a midi file of the tune, so you can learn it if you don't know it.
