Lyrics:

Formulae ueteres exorsismorum et
Excommunictionum
Strigas et fictos lupos credere

Daemon pellem lupinam
In trunco quodum cauae
Arboris occultrandum

Halloween, Halloween,...

Metamorphoses lycanthropie
Possunt inquam
Metamorphoses lycanthropie
Possunt inquam

Halloween, Halloween,...

(The aboce is non-standard Latin.
Translation:
Ancient formulas of exorcisms and
Excommunications
That whitches and those made
Wolves believe
I am now the demon clothed
In wolfskin
Having to hide in the hollow of a tree
I say werewolves can change shapes.)
