Though song-and-dance numbers have never fared well on Oscar night, they reach a nadir when Snow White (actress Eileen Bowman) and a clearly embarrassed Rob Lowe duet on ''Proud Mary.'' It's so tacky it's literally illegal Disney later threatens to file a lawsuit but changes its tune after the Academy apologizes.
