In 1819 Anton Diabelli, a publisher and music teacher, sent out a little waltz tune to every composer and virtuoso he thought worthy, inviting them to write one variation which would be published in a collection he was going to call Der Vaterländische Künstlerverein ("The Patriotic Culture Club"). Eventually he collected 52 responses and published them in 1824, excluding those by Beethoven.
Beethoven had started by pushing the little tune aside with contempt. Then he took it out again, and in 1822 and 1823 put together the "33 variations on a waltz by Diabelli" that is one of the great masterpieces of the piano repertoire. It demolishes Diabelli with glorious exaggeration.
So, what you have to do is to find somebody who received an invitation from J.P.Winkler to write something, and who, like Beethoven, returned far more than he was asked for and, in the process, created a comic masterpiece. J.P.Winkler was an American journalist, and the person he wrote to was not a musician.
Solution: P.G.Wodehouse.
J.P. Winkler was a journalist who used to send a questionnaire to famous
people on their seventieth birthdays, and use their answers in his 'Over
70' column. Wodehouse responded by writing a book,
'Over Seventy', his autobiography.
