Tex Beneke is whistling (whistlewhistlewhistle)...

Glenn Miller: Hello there, Texas, whatcha say?
Are you whistling in the dark just to scare the ghost away?

Tex Beneke: I know there's something following me that I can't see
Someone sure laid an awful hex on me!

Glenn Miller: A hex? Ah, Tex, that's pretty far-fetched.
Man, I'd say you're just a little bit tetched!

Tex Beneke: You'd got a load of what I saw last night
You'd pass the Yankee Clipper on its maiden flight!

Last night I saw upon the stair
A little man who wasn't there
He wasn't there again today
Oh, how I wish he'd go away...

When I came home last night at three
The man was waiting there for me
But when I looked around the hall
I couldn't see him there at all!

Go away, go away, don't you come back any more!
Go away, go away, and please don't slam the door... (slam!)

Last night I saw upon the stair
A little man who wasn't there
He wasn't there again today
Oh, how I wish he'd go away!
