Written by Bob Welch.

Goin' in a straight line all night

Finally come to that house on the right

Parked out in the front is somebody's Benz

She's sneakin' around with her old boyfriends

(chorus)

You can't do that, oh no

You can't do that, I'm gonna let you go

You can't do that, whoi do you think I am

You can't do that, with another man

She been tell little lies

That slightly white

Doin' anything to stay out all night

Guess I should had a suspicious mind

Cause if you fool around then you're gonna find

(repeat chorus)

You can't do that.....(repeat chorus & fade)
