Lyrics:

Good evening
This is George Gershwin speaking
The orchestra just played my song 'Mine'
Tonight I'm going to play you my latest composition
Which I wrote a few months ago down in Palm Beach, Florida
This is a composition in the form of variations on a tune
And the tune is 'I Got Rhythm'
I think you might be interested to hear about
A few of the variations we're going to play
After an introduction by the orchestra
The piano plays the theme rather simply
*Plays the piano*
Like that
The first variation is a very complicated rhythmic pattern
Played by the piano while the orchestra takes the theme
Against that the orchestra fits in the tune
The next variation is in waltz time, and the third is a Chinese variation
In which I imitate Chinese flutes played out of tune, as they always are
Like this
*Plays the piano*
Next, the piano plays a rhythmic variation
In which the left hand plays the melody upside down
While the right plays it straight
On the theory that you shouldn't let one hand know what the other is doing
Like this
*Plays the piano*
Then comes the finale
Now after all this information about 'Variations on 'I Got Rhythm''
How about hearing it?
