Factually wrong. It's both a song and a dance

"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"

Fun fact, Soulja Boy ripped off the Monster Mash when he created the dance that shares his name

False.

It's a blitz.

... a ballroom blitz.
