Stevie Wonder is playing a concert in Tokyo, and asks for requests from the audience.
Little old Japanese guy stands up and says 'Play a jazz chord!!'
Stevie is quite impressed by the man's knowledge of his musical abilities, so launches in to an extended jazz solo..the crowd goes wild.
Little Japanese guy 'No, no..play a jazz chord!!' Irritated, Stevie tries again, with some wild solo-ing.
Again..'Play a jazz chord!!'
Stevie's had enough now 'OK smart arse, you come up and do it if you're so clever!'
'No, no' explains the old guy...
''Play a jazz chord to say I ruv you!!'
