recorded nearly a year before all other selections, "last night when we were young" was difficult, according to riddle, because about thirty takes were used. the recording uses a "low-key" coda, emphasizing strings and horns, and a brief guitar solo. sinatra was involved in the production and felt that the guitar solo needed to be slowed considerably. he held riddle and the musicians in high esteem, so he talked with guitarist george van eps about the change, then discussed it separately with riddle. van eps commented, "frank was loaded with things like that." the finale is a "cataclysmic climax." sinatra recorded the song with an arrangement by gordon jenkins for the album "september of my years" (1965). "last night" was written for the movie "metropolitan" (1935) but was cut from the final version, appearing only as an instrumental during the credits. the song includes advanced harmonic progressions and a juxtaposition of chromaticism and octave leaps.
