A jazz chord

Stevie Wonder is playing his first ever gig in Tokyo and the place is
absolutely packed to the rafters.
In a bid to break the ice with his new audience he asks if
anyone would like him to play a request.
A little old Japanese man 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 .
Absolutely amazed that this guy knows about Stevie's varied musical career, the
blind impresario starts to play an E minor scale and then goes into a
difficult jazz melody for about 10 minutes.
When he finishes the whole place goes wild.
But, ...........
The same  little old man jumps up again and shouts loudly and impatiently.. "No, no, ......play a Jazz chord, ....play a Jazz chord".
A bit pissed off by this, Stevie, being the professional that he
is, dives straight into a jazz improvisation with his band around
the really difficult B flat minor chord and really tears the place apart. The crowd goes
wild with this impromptu show of his superb  technical expertise.
The little old man jumps up again. "No, no...... Play a Jazz chord, play
A jazz chord".
Well and truly p....d off that this little guy doesn't seem to
appreciate his jazz playing ability Stevie says to him from the stage
"OK smart ass. You get up here and do it !"
The little old man climbs up onto the stage, takes hold of the
mike and starts to sing .....................
" A jazz chord to say I ruv you........... "
