Yes,Rapparee, a truly great song.

The one I am remembering is about wildfire fighters. In fact I think I found it (Wikipedia)

The Mann Gulch fire was the subject of Norman Maclean's book Young Men and Fire,[9] which was published after his death. The book won the National Book Critics Circle Award for non-fiction in 1992.

Norman Maclean's son John wrote a book in 2003 titled Fire and Ashes: On the Front Lines Battling Wildfires, and it also includes a section on the Mann Gulch Fire. In 2004, John N. Maclean also published an article called "Fire and Ashes: The Last Survivor of the Mann Gulch Fire," in Montana: The Magazine of Western History. The article was adapted from the Mann Gulch section of his book, in which he interviewed Bob Sallee, the last remaining survivor of the fire.[10]
Folk songs

James Keelaghan wrote a song about this fire entitled "Cold Missouri Waters" after being inspired by Young Men and Fire. The song was covered by Richard Shindell, Dar Williams, and Lucy Kaplansky on their album Cry Cry Cry. It was also covered by Hank Cramer in his album, Days Gone By. It is sung from the perspective of foreman Dodge, lying on his deathbed dying of Hodgkin's disease five years after the fire. It imagines Dodge saying of his decision to set the escape fire:

"I don't know why, I just thought it. I struck a match to waist-high grass, running out of time. Tried to tell them, 'Step into this fire I set. We can't make it, this is the only chance you'll get.' But they cursed me, ran for the rocks above instead. I lay face down and prayed above the cold Missouri waters."

Ross Brown, a musician/songwriter from Townsend, MT (about 35 miles south of Helena) wrote another song entitled "The Mann Gulch." A scratch version of this song is available on YouTube.

The song also has been recorded on Black Irish Band's album "Into the Fire" released in 2007. The album is all songs about firefighters. The album also features Michael Martin Murphey. Underneath Montana Skies is another song about the Mann Gulch fire [11] written by Patrick Michael Karnahan also on this album.
