Superstition by Stevie Wonder is one of those songs that got a whole generation of youngsters dancing. I read a great post by slicethelife about this classic song.
Dave commented that Stevie played an instrument called the clavinet to produce this masterpiece.
There we can see Stevie Wonder, displaying his considerable mastery of this unusual instrument on Soul Train. The interview with Stevie Wonder, gives terrific insight into both Stevie and this amazing song.
Dr Mix gives a history of the clavinet here.
