He's a real nowhere Man,
Sitting in his Nowhere Land,
Making all his nowhere plans
for nobody.

Doesn't have a point of view,
Knows not where he's going to,
Isn't he a bit like you and me?
Nowhere Man, please listen,
You don't know what you're missing,
Nowhere Man, the world is at your command.

(Lead Guitar)

He's as blind as he can be,
Just sees what he wants to see,
Nowhere Man can you see me at all?
Nowhere Man, don't worry,
Take your time, don't hurry,
Leave it all till somebody else
lends you a hand.
