If you've seen or read Ghost World, you probably remember the "A Smile and a Ribbon" 45 that had special significance for Enid. Basic Hip Digital Oddio has a page dedicated to the singers of that tune, a '50s sister act called Patience and Prudence. There's a short bio, and some mp3s, including "We Can't Sing Rhythm and Blues" (they can't) and "Very Nice is Bali Bali" (an only-in-the-fifties gamut-run of Oriental stereotypes).
