The World We Knew is the thirty-sixth studio album by Frank Sinatra, released in 1967 on Reprise Records. It was produced by Jimmy Bowen and recorded at Western Recorders in Hollywood between January and May 1967.
The album includes the hit song 'Somethin' Stupid', a duet with his daughter Nancy Sinatra, which reached number 1 on the Billboard Hot 100 and UK Singles Chart. The song was written by Carson Parks and originally recorded by him and his wife Gaile Foote in 1966.
The album's title comes from the song 'The World We Knew (Over and Over)', an English adaptation of the German tune 'Über den Wolken' by Bert Kaempfert. The record features a soft, romantic orchestral sound characteristic of Sinatra's productions at the time.
