91287 Simon-Garfunkel           Discovered 1999 Mar. 21 by C. Jacques at Wykrota Observatory-CEAMIG.
Simon and Garfunkel, both born in 1941 and bred in Queens, New York, became one of the most successful duos in the history of popular music. Their magic is heard through the beautiful high tenor voice of Garfunkel, as it gently wraps around Simon's natural talent of combining poetic lyrics with memorable melodies.
