The Evil Emperor's Tool, part 1

[A Star Wars parody of "Another Brick in the Wall, part 1" by Pink Floyd]

Vader hunts for the rebels
Searching for a Skywalker
A signal from an icy planet

Vader, how you know Luke's hiding there?
Vader, how d'ya know Luke's hiding there?

Ozzel fool, it was just the Emperor's tool
Ozzel fool, we are all the Emperor's tool
