Somebody Nobody Knows lyrics

Alone in a barroom a young girl is sittin'
and smilin' at nothing at all.
And she smiles now and then
at the eyes of the men
in the mirror that hangs on the wall.

She's waitin' for someone and knowin' there's no one
who cares if she comes or she goes;
just a soul in the shadows
the world never sees,
she's somebody nobody knows.

Chorus:
Someone no one's ever known
smiling where no one can hear,
somebody's dying alone
in a city where nobody cares.

Down in the gutter and old man had fallen
like somethin' the world threw away.
And the late crowd was leavin'
and nobody even
took time to look down where he lay.

The old man was cryin' and helplessly tryin'
to wipe off the stains from his clothes;
just a soul in the shadows
that life left behind,
he's somebody nobody knows.

Someone no one's ever known
cryin' where no one can hear,
somebody's dying alone
in a city where nobody cares.
