 Film is based so exactly on the courtship of Ruby Keeler (qv) and  Al Jolson (qv) that Jolson, having read the script, knocked out  Walter Winchell (qv) when they met accidentally at the Hollywood  American Legion stadium on the night of July 21, 1933. Keeler, who  was a dancer at Texas Guinan (qv)s nightclub, was dating gangster  Larry Fay when she met Jolson. Fay visited Jolson after hearing of  this just to tell him that he could marry her.
