There's A Bat Testo

There's a bat crawling on my neck, and it's a big one, and it's got
your number, and it's got mine too
and it'd be quite content to feast on you, oh my work, it's crawling on
my neck, then he spoke to me, 'horror, horror!'
what I though it was at first wasn't what I though at
first, there's a bat on my neck
