Brahms:Variations on a Theme by Haydn Op56a: Theme and Var.VI-horn quartet

I have arranged the Theme and Variation Vi of Brahm's "Theme and Variations on a Theme by Haydn (St. Anthony Chorale)" for horn quartet.
The theme is well known and needs no further comment.
  Variation VI. is the variation that horn players love to play in the original orchestral composition. It's the big moment!! Originally scored for Hn 1/2 in Bb basso, Hn 3 in F and Hn 4 in Eb, I have arranged it for 4 hns in F. The original parts are mostly there... Quite short, about 1 min 30...great fun to play.
