Jazz vocalist Bobby McFerrin
, best known for his #1 1988 novelty tune "Don't Worry, Be Happy," is the son of Robert McFerrin
, who in the 1950s was one of the first African-Americans to sing regularly with the Metropoliton Opera in New York. The elder McFerrin was also the singing voice of Sidney Poitier in the movie version of Porgy and Bess. Bobby's mother was also a classically trained musician who served as head of the music department of a college in Fullerton, California. All of which explains why Bobby may occasionally be seen as a guest arranger/conductor for symphony orchestras around the country.
