He needs me
He doesn't know it, but he needs me
And so no matter where he goes
Though he doesn't care
He knows that I'm here
He needs me
I ought to leave him, but he needs me
I know that I'm not very bright
Just to tag along
Oh, but right or wrong
I'm his and I'm here
And I'm gonna be his friend or his lover
'Cause my one ambition is
To wake him and make him discover
That he needs me
I've got to follow where he leads me
Or else he'll never know that I need him
