Halloween // Help me help her!

Got a huge favor to ask. My girl is having a rough time lately but she is SUPER into Halloween. Lately she's been trying to remember this Halloween song and its driving her nuts. All she can remember is some bits of the lyrics that went "my grim ghastly ghouls" and something about getting "necked by dracula". I know it's an odd request but its a small thing that would really cheer her up. Thanks!
