Lyrics
Bernard: 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 The 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 Wolfman 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 played the mash, they played the monster mash The monster mash, it was a graveyard smash They played the mash, it caught on in a flash They played the mash, they played the monster mash

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

It's now the mash, it's now the monster mash The monster mash, and it's a graveyard smash It's now the mash, it caught on in a flash It's now the mash, it's now the monster mash

Now everything's cool, Drac's a part of the band And 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 Boris sent you

Then you can mash, then you can monster mash The monster mash, and do my graveyard smash Then you can mash, you will catch on in a flash Then you can mash, then you can monster mash

Wah-ooh, argh, monster mash, wah-ooh Easy, Igor, you impetuous young boy Argh, mash good, mm, argh Monster mash, wah-ooh, monster mash, wah-ooh
