There's A Bat lyrics

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
Oh my
Oh my word
Crawling on my neck
Then he spoke to me
Horror horror
What I saw wasn't quite what I thought it was at first
There's a bat on my neck
