Bobby McFerrin — American Musician born on March 11, 1950,

Robert Keith "Bobby" McFerrin, Jr. is an American vocalist and conductor. He is best known for his 1988 hit song "Don't Worry, Be Happy". He is a ten-time Grammy Award winner, who is known for his unique vocal techniques, such as singing fluidly but with quick and considerable jumps in pitch—for example, sustaining a melody while also rapidly alternating with arpeggios and harmonies—as well as scat singing, polyphonic overtone singing, vocal basslines, and improvisational vocal percussion. He is widely known for performing and recording regularly as an unaccompanied solo vocal artist. He has frequently collaborated with other artists, from both the jazz and classical scenes...

The true musician is to bring light into people's hearts.
If I can bring joy into the world, if I can get people to stop thinking about their pain for a moment, or the fact the tomorrow morning they're going to get up and tell their boss off... then I'll be successful.
Seriously though, my father was the first African American to sign a contract with the Metropolitan Opera so I grew up with classical music and jazz in the home all the time.
Then when I was in grammar school I played the clarinet, and then, after clarinet I played the flute in college orchestra - besides singing in the college chorus and things like that.
Well, I started conducting kind of by accident. I wanted to give myself a special birthday present for my fortieth birthday, and I was living in San Francisco at the time and I started attending some of the concerts and then simply dropping hints.
