Lyrics:

Under my thumb's a siamese cat of a girl,
Under my thumb she's the sweetest pet in the world.

It's down to me the way she does just what she's told,
It's down to me, the change has come,
She's under my thumb.

Under my thumb her eyes are just kept to herself
Under my thumb, well, I--I can still look at someone else.
It's down to me the way she talks when she's spoken to
It's down to me the change has come,
She's under my thumb.
