Ruth Etting Maybe-Who Knows Original Ziegfeld Sheet Music In 1955 Doris Day and James Cagney set the world on fire with their emotionally charged bio-pic for the tragic life of famous jazz-singer Ruth Etting. She rose from the bottom, to become a major star with the Ziegfeld follies, all the while trying to survive the storm of her tempestuous horrifically violent marriage to ruthless gangster Marty "The Gimp" Snyder. She tried to use her songs to express the hidden (and not so hidden) secrets of her abuse. One of her most famous is "Maybe! - Who Knows?" that she sang in the smash hit Ziegfeld Show "Whoopee". This is a rare original sheet music from that song. It's in excellent condition.
