Though hers is the central character in the story, Grace Kelly does not sing a solo. Indeed, but for accompanying Bing Crosby on "True Love" and drunkenly shouting, "Sensational," she wouldn't sing at all (rare for a musical).
Features the song "Who Wants To Be a Millionaire?" which gave the successful TV quiz show its title.
The song "Well, Did You Evah?" (from a previous Cole Porter musical) was added at the last minute when it was realized that there wasn't a song for Bing Crosby and Frank Sinatra to sing together.
The song True Love, written by Cole Porter especially for the movie, was a million seller and both Grace Kelly and Bing Crosby were awarded platinum records for the song. This is the only platinum record ever given to sitting royalty as Grace Kelly had become Princess Grace by the time it was awarded.
