I watched the Toby Keith movie Broken Bridges after the Opry last night. I have watched bits of it but never the entire movie.
At the military funeral this song started to play and I thought I had heard it before and then the singing started and sure enough it was Sonya Isaacs with Vince singing harmony to the song The Battlefield. I think Sonya and Vince wrote or arranged the song. It is on her album that he produced for her.
I checked on the soundtrack for the movie and they have the song on the soundtrack and I noticed at the end of the movie Sonya and Vince were in the musical credits.
So if any one watches the movie be sure and listen at the military funeral service and you will hear a little bit of Vince singing harmony with Sonya.
