Language focus: saying "hello" and introducing Halloween characters

Lyrics:

Hello, my friends. (Hello, my friends.)
I'm so happy to see you.
Hello, my friends. (Hello, my friends.)
Let's go trick-or-treating.

Witches and ghosts. (Witches and ghosts.)
Cowboys, pirates, and monsters.
Spiders and bats. (Spiders and bats.)
Let's go trick-or-treating.

Hello, my friends. (Hello, my friends.)
I'm so happy to see you.
Hello, my friends. (Hello, my friends.)
Let's go trick-or-treating.
