Gotta re-mention "With 'Er 'Ead Tucked Underneath 'Er Arm (Anne Boleyn"), "Witchy Woman," "Monster Mash," "Dry Bones," and "Spooky."

How about "Thriller"?
also The Funeral March for A Marionette (is that the title?)

Then there's the old camp song,

Did you ever think when the hearse goes by
that you might be the next to die?
They wrap you up in a long, white sheet
and put [a tombstone?] at your feet.
The worms crawl in, the worms crawl out
and [something something] like sauerkraut.
Your stomach turns a glossy green
and puss flows out like whipping cream.
You sop it up with a piece of bread
And that's what you eat when you are dead,
So, when I die, don't bother to bury me at all,
Just pickle my bones in alcohol!
