So, here's what I hear on the Unger/Mason recording:

RELAX YOUR MIND
(Huddie Ledbetter)
[as recorded by Jay Unger & Molly Mason on their CD by the same name]

Oh, when you're drivin' in your automobile,
Keep your hands on that steerin' wheel;
Sometime, you got to relax your mind, your mind.

Relax your mind, relax your mind,
And you'll feel so fine sometimes,
Sometime, you got to relax your mind, your mind.

Now, when the light turns green,
You put your foot on the gasoline,
Sometime, you got to relax your mind, your mind.

And when the light turns red,
Put your foot on the brake instead;
Sometime, you got to relax your mind, your mind.

Relax your mind, relax your mind,
Makes you feel so fine some time,
Sometime you got to relax your mind.

When the traffic light turns blue,
What in the world are you gonna do?
Sometime, you got to relax your mind, your mind.

[instrumental break]

Sometime you got to relax your mind.
(Repeat first verse)
