June 21st, has a special meaning for a certain song...  There is a documentary on Neflix "It All Begins With A Song: The Story of Nashville Songwriters."   It is a few years old.  Where if you would like to dig in deeper on the story it is amazing.  The documentary hits on various songs from country, rock pop really all genres.  The writers who wrote this song have a very interesting back story. 

The story comes about from Paul Monti's son Jared.  It began with a line from an interview one of the writers heard.  It was written, a demo made and an artist was picked out...  The writers after the song went to #1 they wanted to play it for the father of the fallen soldier.  There are a lot of coincidences with this song.  Like it was written on the same day the solider passed 2 years prior. That day was June 21st. 

I've only watched the documentary once.  The date stuck with me... June 21st.  

The writers have told this story many times.  The documentary is good with a number of country artists.  Maybe worth a watch.  Here is the story from one of the writers below and part of the documentary.
