Arguably the finest single interpretation on Songs For Swingin’ Lovers, “I’ve Got You Under My Skin” is a magnificent song, a song recorded by literally hundreds of jazz vocalists and crooners, yet which Frank Sinatra sings it, it’s indisputably his own, and it’s a masterpiece. Indeed, it’s the song’s arrangement that is primarily compelling. According to legend, Nelson Riddle finished the arrangement in a cab when driving to the studio and, after the first run through, all the musicians stood up in unison and applauded. It’s certainly easy to understand their reaction. Arguably Riddle’s finest three minutes, the song is a series of peaks, which keep building and building until it appears even Sinatra’s vocal is dwarfed by the arrangement. Having said that, the way Sinatra sings, with humour, lightness and, above everything, fluidity, is simply mesmerising. “I’ve Got You Under My Skin” is perhaps Sinatra’s and Riddle’s greatest single accomplishment.
