For day 2 of Classical Music in Popular Songs Week, it's the Beach Boys' Lady Lynda based on Bach's very familiar Jesu, Joy of Man's Desiring... which, in turn, was the name of a famous piano transcription of the final Chorale (Jesus bleibet meine Freunde) from cantata BWV 147, Herz und Mund und Tat und Leben. (This performance is Ton Koopman conducting what I think must be the Amsterdam Baroque Orchestra and Choir.)
