Poetry Friday: Grim, Grinning, Ghosts

So, I normally don't participate in Poetry Friday, but I had the perfect one for Halloween so I decided to get in on the spirit (pun not intended....).

These are actually song lyrics, but I think that should count as poetry too. Bonus points if you can leave me a comment and tell me where this song is from! :-)

Grimm, Grinning, Ghosts
When the crypt doors creak,
And the tombstones quake.
Spooks come out for a swinging wake.
Happy haunts materialize,
And begin to vocalize.
Grim grinning ghosts come out to socialize.

Now don't close your eyes,
And don't try to hide.
Or a silly spook may sit by your side.
Shrouded in a daft disguise,
They pretend to terrorize.
Grim grinning ghosts come out to socialize.

As the moon climbs high o'er the dead oak tree,
Spooks arrive for the midnight spree.
Creepy creeps with eerie eyes,
Start to shriek and harmonize.
Grim grinning ghosts come out to socialize.

When you hear the knell of a requiem bell,
Weird glows gleam where spirits dwell.
Restless bones etherialize,
Rise as spooks of every size.

(Maniacal laughter)

If you would like to join our jamboree,
There's a simple rule that's compulsory.
Mortals pay a token fee.
Rest in peace, the haunting's free.
So hurry back, we would like your company.
