Aired last night, with Sinatra, Gene Kelly and Esther Williams. Question: shortly after the opening sequence when Kelly and Sinatra are riding on the train to Florida for spring training, it appears that Danny Kaye, or a close ringer, is seated behind them reading a paper or magazine (back left corner of screen). He never speaks or is seen again in the film. Can anyone verify or refute? Thx. Gedley
