I transcribed this from the recording found at YouTube:

SALLY SUNSHINE
(Geoff Stevens, Les Reed)
As sung by the Mills Brothers

1. You're the eldest of five, Sally Sunshine,
And a room in the ghetto is your home.
In your young teenage life, you must act like a wife,
'Cause your dad can't do it all alone.

2. You don't know what it's like to buy candy
Or to ride a pony in the park,
And you don't ever play with the kids round your way
'Cause their folks say your skin is kinda dark.

CHORUS: But you smile all the while, Sally Sunshine,
And you laugh when you really oughta cry.
Don't give up; keep it up now, Sally Sunshine.
The sun is gonna shine upon you by and by.

3. While you care for your brothers and your sisters,
All we do is turn our heads away,
'Cause we might feel ashamed if we had to explain
How the world could have treated you this way.

CHORUS: Yes, you smile....

4. We've got so much to learn, Sally Sunshine.
You're the one who can tell us what to do.
Carry on, little girl; show the rest of the world
How to love and live our lives like you.

CHORUS: 'Cause you smile....

CHORUS: Yes, you smile....

There are other songs called SALLY SUNSHINE, notably one written by Phil Everly.

If I wanted to sing this song today, I would find a way to change or remove the phrase "act like a wife." It adds a hint of incest that I don't think was intended by the songwriters. But, alas, we are too aware of incest today to let that go unnoticed. Anyway, the rest of the song describes her acting like a mother, not a wife.

The songwriters are British. Cliff Richard recorded this song in the UK. I don't know if his words were different. Would a British singer or songwriter use the word "ghetto"?
