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. On the UK Singles Chart, the song reached number 2 during its fifth week on the chart. At the 1989 Grammy Awards, "Don't Worry Be Happy" won the awards for Song of the Year, Record of the Year, and Best Male Pop Vocal Performance. The song's title is taken from a famous quote by Meher Baba. The original music video stars Robin Williams and Bill Irwin. The "instruments" in the a cappella song are entirely overdubbed voice parts and other sounds made by McFerrin, using no instruments at all.
