what is the name of this song??

There is a scene In a Bordello. Kaye, Cole, and an unnamed worker to put it genteel are singing a song at the piano... it starts.." Why are you weepin', weepin'...sister...." and includes a melancholy.." all your tomorrows were yesterday..." such a simple Brothel song, as it is clear it is sung to a prostitute..." you've bartered your graces for silks and for laces..." etc...


I have been all over wikipedia and even the Nat King Cole soundtrack that has the ballad, lacks this song.. if anyone can help me i would appreciate it.
