"You're All the World to Me" is an American song written in 1950 by composer Burton Lane and lyricist Alan Jay Lerner for the 1951 MGM musical, Royal Wedding.
[1] The lyrics by Lerner, who also wrote the story and screenplay, give song-and-dance man Tom Bowen, played by Fred Astaire, the opportunity to proclaim his love for Anne Ashmond (Sarah Churchill) while dancing on the walls and ceiling of a custom-made set which, along with an attached camera and camera operator, rolled on an axis to provide the anti-gravity illusion.
The music to the song was used again in 1953 for the title credits and dance routine that opened MGM's Torch Song, which starred Joan Crawford.
