Dying to figure out who does the original song for this house tune that DJ Aristotle has been pumping for months at Fluid in Toronto.  I've had no luck asking him myself and noone else in the club seems to know either, or they won't tell... snobs.  I do know that i've heard it before as a female acapella.  Lyrics go...

You must be somebody's baby
'Cause I can't see how anybody wouldn't want to be your lady, baby

Is this what you are talking about?

Somebody's Baby by Jackson Browne

Well, just - a look at that girl with the lights comin' up in her eyes.
She's got to be somebody's baby.
She must be somebody's baby.
All the guys on the corner stand back and let her walk on by.
She's got to be somebody's baby.
She must be somebody's baby.
She's got to be somebody's baby.
She's so fine.
She's probably somebody's only light.
Gonna shine tonight.
Yeah, she's probably somebody's baby, all right.

I heard her talkin' with her friend when she thought nobody else was around.
She said she's got to be somebody's baby; she must be somebody's baby.
'Cause when the cars and the signs and the street lights light up the town,
She's got to be somebody's baby;
She must be somebody's baby;
She's got to be somebody's baby.
She's so....
She's gonna be somebody's only light.
Gonna shine tonight.
Yeah, she's gonna be somebody's baby tonight.

I try to shut eyes, but I can't get here outta my sight.
I know I'm gonna know her, but I gotta get over my fright.
We'll, I'm just gonna walk up to her.
I'm gonna talk to her tonight.
Yeah, she's gonna be somebody's only light.
Gonna shine tonight.
Yeah, she's gonna be somebody's baby tonight.
Gonna shine tonight, make her mine tonight.

Thanks for the effort but that is definitely not the song... :-/
