Jazz cord

Stevie Wonder is playing his first gig in China and the giant auditorium is packed to the roof with excited fans.
In a bid to break the ice with the huge audience, he asks if anyone has a request. One chap jumps out of his seat in the first row and shouts at the top of his voice: "Play a jazz chord! Play a jazz chord!"
Amazed that this guy knows about the jazz influences in Stevie's career, the blind entertainer starts to play an E minor scale and then swings into a difficult jazz melody for about ten minutes. When he finishes the whole place goes absolutely wild with excitement!
But, the same chap jumps out of his seat again and shouts: "No, no, play a jazz chord; play a jazz chord!"
A bit cheesed off by this, Stevie, being the professional he is, dives straight in to a jazz improvisation with his band around the B flat minor chord and really tears the place apart. The crowd goes completely crazy with this impromptu show of Stevie's musical expertise!
But, still the little Chinese guy jumps up again and shouts "No, no. Play a jazz chord; play a jazz chord!"
Stevie is getting really fed up now that this chap doesn't seem to appreciate his playing ability and shouts to him from the stage: "Okay, wise guy, you get up here and do it!"
The little bloke climbs onto the stage, grabs hold of the mike and starts to sing  "A jazz chord to say, I ruv you...."
