I'm trying to find the lyrics of a Halloween song I learned in elementary school music class. It was in our music book. The lyrics are below with a blank where the missing words would be located. Thank you for your help.

Midnight winds upon the air
Ghosts glide out from everywhere
Green-eyed ghouls dance round and round
______________ without a sound
But with dawn they will sink
back into the ground.

There's a witch upon her broom
Flying way up to the moon
How she swishes through the sky
While the bats go flying by
But with dawn she will sink
back into the ground.
