Witches' Brew

What is it about kids and that Witches' Brew song?
They all LOVE it!  (Ok...So do I!)

"Finger nails, lunch pails, apple cores, too...

Stir them in my witches’ brew!
I got maaaaagic, Alakazamakazoo."

The boys' school plays this every year at the Halloween parade, which is really nothing more than a bunch of elementary kids marching around, proud as can be, in their crazy Halloween costumes.

And every single one of them jumps in with:
"...What's it gonna to do you? BOO!"

(sniff)

Is it weird for me to be nostalgic about something that happened an hour and half ago?
