Good evening!

I was working in the lab late one night
When my eyes beheld an eerie sight
For my monster from his slab began to rise
And suddenly to my surprise

(He did the mash)
He did the monster mash
(monster mash)
It was a graveyard smash
(He did the mash)
It caught on in a flash
(He did the mash)
He did the monster mash

From my laboratory in the castle east
To the master bedroom where the vampires feast
The ghouls all came from their humble abodes
To get a jolt from my electrodes

(They did the mash)
They did the monster mash
(The monster mash)
It was a graveyard smash
(They did the mash)
It caught on in a flash
(They did the mash)
They did the monster mash

The zombies were having fun
The party had just begun
The guests included The Wolf Man
Dracula and his son

The scene was rockin', all were digging the sounds
Igor on chains, backed by his baying hounds
The coffin-bangers were about to arrive
With their vocal group, "The Crypt-Kicker Five"

(They did the mash)
They did the monster mash
(monster mash)
And it's a graveyard smash
(They did the mash)
It caught on in a flash
(They did the mash)
They did the monster mash

Out from his coffin, Drac's voice did ring
Seems he was troubled by just one thing
He opened the lid and shook his fist
And said, "Whatever happened to my Transylvania twist?"

(Mash)
It's now the monster mash
(monster mash)
And it's a graveyard smash
(He did the mash)
It caught on in a flash
(Oh he did the mash)
He did the monster mash

Everything's cool, Drac's a part of the band
My monster mash is the hit of the land
For you, the living, this mash was meant too
When you get to my door, tell them Only sent you

(Mash)
Then you can monster mash
(monster mash)
And do a graveyard smash
(He did the mash)
They caught on in a flash
(He did the mash)
You can monster mash!
