'Cecilia' (1970) is a playful, rhythmic folk-pop song by Simon & Garfunkel. Contrary to its upbeat tune, it's about a lover's deceit ('Cecilia, you're breaking my heart'). The recording is notable for how they created the beat – in one session Simon, Garfunkel, and friends stamped their feet and slapped their legs and a piano bench to get the percussion. The catchy chorus and whistle hook helped it reach the Top 5 on the charts. Its blend of joyful music and bittersweet lyrics has made 'Cecilia' a sing-along favorite.
