it was a graveyard smash
it caught in a flash

a party of monsters guest included wolfman dracula and his son

The coffin-bangers arrived With their vocal group, "The Crypt-Kicker Five"

The monster mash is the hit of the land
For you, the living, this mash was meant too

The zombies were having fun the party had just begun they did the mash they did the monster mash
