Dropkick Murphys - Third man in lyrics

My friends, my town, Comaraderie We'll never finish last We stood as one where are they now We grew up fast Too young to know or really give a s*** The past has left us worse for wear Be strong and stand Stand up like a man Your concept of Friendship isn't right Third man in is how you show your care Nothing else matters but the fight Some will survive I hope I'm one of them Things aren't what the used to be It makes me sick Our bond has broke and we aren't what we were It's time to face life on my own
