That is weird - Your first post has no link. But it works on this one - Great to hear this for a second time this morning. As I said at the MM Forum earlier, this was a great way to start the day. And I love the title - suits its old fashioned charm perfectly.
As far as I can remember (my life on this forum is not that long), I've never heard a horn duet. It comes as a nice and welcome surprise. And you did a wonderful job. Would you publish the score for the benefit of many horn classes?
