Just a small town girl

Livin' in a lonely world

She took the midnight train goin' anywhere

Just a city boy

Born and raised in south Detroit

He took the midnight train goin' anywhere

A singer in a smoky room

A smell of wine and cheap perfume

For a smile they can share the night

It goes on and on, and on, and on

Strangers waiting

Up and down the boulevard

Their shadows searching in the night

Streetlights, people

Living just to find emotion

Hiding somewhere in the night

Working hard to get my fill

Everybody wants a thrill

Payin' anything to roll the dice

Just one more time

Some will win, some will lose

Some were born to sing the blues

Oh, the movie never ends

It goes on and on, and on, and on

Strangers waiting

Up and down the boulevard

Their shadows searching in the night

Streetlights, people

Living just to find emotion

Hiding somewhere in the night

Don't stop believin'

Hold on to the feelin'

Streetlights, people

Don't stop believin'

Hold on

Streetlights, people

Don't stop believin'

Hold on to the feelin'

Streetlights, people
