See media help . </Td> </Tr> <P> The "instruments" in the a cappella song are entirely overdubbed voice parts and other sounds made by McFerrin, using no instruments at all; McFerrin also sings with an affected accent . </P> <P> The comedic original music video for the song stars McFerrin, Robin Williams, and Bill Irwin, and is somewhat shorter than the album version . </P> <P> Originally released in conjunction with the film Cocktail in 1988, the song originally peaked at No. 88 on the Billboard Hot 100 . The song was re-released the same year and peaked at No. 1 on September 24, 1988 displacing "Sweet Child o' Mine" by Guns N' Roses which had previously held the No. 1 spot . </P>
