Don't Worry, Be Happy Don't Worry, Be Happy "Don't Worry, Be Happy" is a popular worldwide hit song by musician Bobby McFerrin. Released in September 1988, it became the first "a cappella" song to reach number one on the "Billboard" Hot 100 chart, a position it held for two weeks. The Indian mystic and sage Meher Baba (1894–1969) often used the expression "Don't worry, be happy" when cabling his followers in the West. In the 1960s, the expression was printed up on inspirational cards and posters of the era. In 1988, McFerrin noticed a similar poster in the apartment of the jazz duo Tuck
Bobby McFerrin was already 32 years old. Before that, he had spent six years developing his musical style, the first two years of which he attempted not to listen to other singers at all, in order to avoid sounding like them. He was influenced by Keith Jarrett, who had achieved great success with a series of improvised piano concerts including "The Köln Concert" of 1975, and wanted to attempt something similar vocally. In 1984 McFerrin performed onstage at the Playboy Jazz Festival in Los Angeles as a sixth member of Herbie Hancock's VSOP II sharing horn trio parts with the Marsalis Brothers.
