This famous recording of Cole Porter’s “I’ve Got You Under My Skin” is considered by many to be Frank Sinatra’s true masterpiece, as well as being one of the all-time great arrangements of the genre, thanks to Nelson Riddle. It was a last minute addition, arranged on the fly, to the classic album Songs for Swingin’ Lovers, and took a highly unusual 22 takes for both Sinatra and the orchestra to master. Riddle remembered it as one of the few times that the members of the band stood up after the first rehearsal and applauded. Of its finish, Will Friedwald, music critic and author of Sinatra! The Song is You, wrote:
…Sinatra returns for an out chorus to end all out choruses: he starts by using [trombone soloist] Bernhart’s highest emotional peak as his own lowest note and builds from there to a musical dramatic climax that fully exploits Cole Porter’s lyric as meaningfully as his melody, combining pure swing with caveman machismo, capable of grabbing even the most Frank-resistant listener way down at the bottom of his soul.
