When Ravenal first meets Magnolia, just after he sings "Where's The Mate For Me?", she mentions that she plays the piano. He asks, "Was that you I heard just now?", but there is no indication in the film that he actually has heard her.

In the original show, Ravenal sings the first verse of "Where's The Mate For Me?", and then hears Magnolia practicing offstage. Then he goes on to sing a part of the song which is not included in the film. Immediately afterwards, his first conversation with Magnolia takes place, and so, in the stage version, the audience knows exactly when he heard her practicing.
