Here is music from Haydn's days!  Composed late in his career, "The London Symphonies" came after the death of Mozart, and before the first symphony of Beethoven, and were literally the pinnacle of the Classical period.  Symphony No. 104 is the most well-known of these and this arrangement is as true to Haydn's original intent as possible.  Your players will capture the bright spirit of the music and rise in their technical and musical levels as they do it.
