One of the few memories I have of grade school is singing this little ditty:

Witches, pumpkin heads, and black cats,
Scary spooks and black bats,
Oh it's Halloween

Halloween's the night
You dress up like a sight
To give your friends a fright
Look out, it's Halloween

Halloween night is the night
When fearful things are seen
Look out, look out, it's Halloween

It might be a round - I can't find two other people who know it so I can't test that theory. Anyone else remember this song?

My favorite Halloween song is Loreena McKennit's "All Souls Night". I remember posting the lyrics to it around this time last year. Wow, I can't believe I've been coming to this site for a whole year! Time flies when you're singing and having fun.
