writer Morrie Ryskind claims he was told that movie audiences  would not accept the musical convention of having an orchestral  background appear from nowhere at the start of a song. For an entire  day, an orchestra was hired to be filmed as playing the background  to the movies love songs, but the movies crew forgot to film them.  The movie went out without the orchestra shots, and, "No one cared,  of course," said Ryskind.
