melm, thanks for the background on "Ashoken Farewell".
When Burns' film "The Civil War" was released I was fascinated by much of the music, so bought the CD soundtrack. But I was particularly taken by "Ashoken Farewell" so also picked up Ungar's Fiddle Fever album which introduced that song. I still find it beautiful and haunting. No matter if it was not written as a tribute to the Civil War and those wounded or killed then, I felt it was a perfect choice by Burns.
