Eons ago, the late Gloria Grahame played Ado Annie in the film version of Oklahoma! (1955). Gloria was tone-deaf, not a singer, and had been dubbed when called to sing in earlier movies. But as the song "I Cain't Say No" is very much a character song, the decision was made that she sing it herself. So the story goes that they sat her in a studio and had her sing a line, record it, then do the next line, record it, painstakingly making sure she stayed on key, and line by line cobbled a complete vocal take.

The result? Seamless perfection, a hilarious and memorable performance and rendition. Decades later, long away from the Hollywood scene, Grahame was pleased as punch when she still received residuals from the movie soundtrack.
