Fun with Haydn

Suppose for a moment, Haydn could write his works once again. Would he be content with them as they are? Or would he change everything about them?

Would he write film scores? Or would he be bored with that? What was his relationship to Mozart like? And what does his student Beethoven think about the opera "Il mondo della luna"? Will they rewrite the work? Was this kind of work as much fun then as it is today?

Herr Haydn will tell all. And plenty of other good stuff from his 77 years.
