"Don't Worry, Be Happy" is the opening tune of a collection of multi tracked songs on which all the voices are Bobby McFerrin's. Five originals including the title track "Simple Pleasures" are interwoven with "Drive My Car" (Lennon/ McCartney), "Good Lovin'," "Susie Q," "Them Changes" (Buddy Miles) and Sunshine Of Your Love. Throughout this recording is the percussive chest thump which Bobby pioneered and really must be considered the origin of innovative vocal percussion which has become so important to contemporary a cappella.
