Largely forgotten, this wistful song is from Rodgers and Hammerstein's Allegro, a musical which ignored plot in favor of telling the story of someone's life. Sinatra rewrites the lyric a little, perhaps unwittingly. He sings "And now at least we've met" but Hammerstein wrote ""And now at last we've met." It's an intriguing change from the idea of fate ("at last") to an understanding that this meeting may not result in a romance.
