The movie event of the Millenium

I chose this song, because its explaining not to give up hope, things will get better, and in the end of the movie we just saw, all the soldiers were singing for hope, letting the other guy (im guessing the lutenent) know that they believe in hope.
WWI is harsh, these people have families. They need hope. Another reason i chose this song.. is because when my grandma was in the hospitol for cancer, she asked me to get her an mp3 player and put one song on there. So we ended up getting her one, and i put this song: Don't stop believin' by journey, and she asked me to put it on repeat so i did and she listened to it over and over again, she said it brought her positive thinking. she died 3 months later than the doctor told her she would.
