We'll start at nine

Next week will be all kinds of dumb
Tonight, we're just having fun

This is fine, at nine

Satan raises his wicked staff
Beneath, the demon cackles swell
Devils join in with their laugh
And merry times are had in hell

Let's wake them up at nine

Halloween comes closer
It's right there, just ahead
In keeping with the spirit
Tonight's things that are dead 

With Vincent Price at nine

I can't believe there's still two months
Left in this year from hell
So I'll just play some music
And you come dance a spell

Scratching an itch at eight

It's going to happen twice this month
We're having a blue moon
At least this kind of thing is rare
(Thus the saying, I presume)
