Macavity: The Mystery Cat (From "Cats")

Macavity's a mystery cat, he's called the hidden paw

For he's the master criminal who can defy the law

He's the bafflement of Scotland Yard, the Flying Squad's despair

For when they reach the scene of crime Macavity's not there!

Macavity, Macavity, there's no one like Macavity
