what is this soul song- What you gonna do when i'm gone?

Question

other lyrics include- what you gonna do on the day, turn my head and walk away

Answer 1

The only lyrics that vaguely matched were these (below)

(What Are You Gonna Do) When I'm Gone
(Smokey Robinson)

What are you gonna do when I'm gone?
Whose shoulder are you gonna cry on?
What are you gonna do on the day
When I turn my head & just walk away?

What are you gonna say to your friends
When the talk around town begins?
Will you tell them how you treated me bad?
Will you tell them how you made me so sad?
You make some people think that you love me a lot
They just don't know you; what they see isn't what we've got

We're happy in the public eye
They think you're such a wonderful guy
But they don't know how much you've lied
& they don't know how much I've cried
You're a real Dr. Jekyll & Mr. Hyde

(instrumental, with backing "ooo"s)

You make a pass at every girl that you see
Then when they hurt you, you come runnin' & crying to me

I comfort you whenever you're low
& you don't have no place you can go
You put your head on my shoulder to cry on
& then you turn around & tell me a lie
& I just can't take it, I've gotta make it, now

(repeat & fade):
What are you gonna do when I'm gone?

Answer 2

I think it's "What Are You Gonna Do When I'm Gone" and it's by Smokey Robinson.

The lyrics are hard to find but you can view them on this site it's the second to last one.
