The producers of the film considered the song uncommercial, however, and deleted it from the print shown at its Royal Command premiere in London.
When Monro, who attended the event, made Black aware of the edit, they successfully lobbied the producers to restore it.
Monro's interpretation appeared over the closing credits in a shortened version recorded especially for the film, which enabled it to qualify for the Academy Award.
Monro's complete commercial recording was released on the film's soundtrack album and became the singer's signature tune for the remainder of his career.
However, Roger Williams recorded a cover that was noted for its use of a male chorus, heard in the second half of the song after the instrumental section.
