A Japanese guy went to a Stevie Wonder concert and kept shouting to Stevie to "Play a jazz chord". Stevie played numerous jazz chords but still the Japanese guy shouted "Play a jazz chord"

Stevie got so fed up with this guy he got a couple of his roadies to lift him up on the stage, gave him a microphone and said, "Now show me what you mean".

The Japanese guy cleared his throat and started to sing, "A jazz chord to say I love you, a jazz chord to say how much I care"..........
