Well, I knew someday
Ruby would be leaving
That she wasn't happy
Living quietly, quietly

Cause she would get that
Bedroom look each morning
And I felt Ruby
Pull away from me

Yeah, so go downtown
At nine o'clock this evening
Walk under that red light
Then down the hall, down the hall
[ Lyrics from: http://www.lyricsfreak.com/j/johnny+cash/see+ruby+fall_20302047.html ]
Look for the highest flying girl
That's Ruby
And if you wait your turn
You'll see Ruby fall

Don't let her know
That you even know me
She'll be trying
To forget it all

And don't tell me how
It was tonight, tomorrow
Cause I don't want to
See Ruby fall

I didn't hold her back
When she got restless
One man is not enough
When she wants it all

Yeah, I let her go
When I saw what she wanted
Cause I don't care to
See Ruby fall
