‘Don’t Worry, Be Happy’ is a song by American musician Bobby McFerrin and is the first a cappella song to reach number one on the Billboard Hot 100. All the sounds in the song were created by McFerrin, who did not use any instruments. ‘Don’t Worry, Be Happy’ won three Grammy Awards in 1989: Best Song of the Year, Best Record of the Year and Best Male Pop Vocal Performance. Arranger Johny Ocean has turned this song into a lively, up-tempo arrangement.
