Gibbs - Kangaroo Cry - NCIS

So it starts as Gibbs quits and how he feels, then he realises what he's left and how he has to live with the pain again. then it kinda jumps to judgment day and it goes through the story line until the end when Gibbs realises that him losing his team was just like him losing his wife and daughter. Yea, the end doesn't really make sence but it seemed to fit. I DONT OWN THE SONG OR NCIS
