O Children (Interpretation) - Harry Potter

If you have seen Harry Potter, and the Deathly Hallows Part 1, you will definitely remember the scene where Harry and Hermione dance to O Children by Nick Cave and the Bad Seeds. If you haven't heard it, you can play it here while reading the rest of this post! :)

The song is intense and makes you sway to the rhythm. This was a powerful scene depicting that the bond they shared wouldn't allow either of them to break even in this plight.

So what happened today is I came across this song and since I found the lyrics very intriguing. Now let us see how it relates to the war in the movie. First of all, the lyrics are from the point of view of the adults: adults who failed to protect their children from the war and its horrible consequences. It's the same in Harry Potter, the adults have failed to protect the younger generation from Voldemort and in the end they are the ones who have to fight something beyond them (it started before they were even born and is so much more powerful). Plus, the adults in this song apologize for failing at protecting them, addressing themselves directly to the children. In the movie, the children (Harry and Hermione (yes they are children, remember they are only 17)) heard the song on the radio, so it's like the adults were talking to them through it.
More than just an apology, the lyrics also encourage the children to 'rejoice' and 'lift up their voice'. There is still hope in the children, even when the adults have failed. This is the case in the movie : adults couldn't destroy Voldemort, their children did. Harry, Hermione and their team were the last hope of the wizardry world.
At the end of the song, it talks about deportation (Hey, little train, we're jumping on. The train that goes to The Kingdom), however they don't seem to lead people to their death but to a certain happiness and freedom, which is weird at first, but then, remember the adults are talking to the children : they give them an illusion because even though they cannot save them, but they can try to keep them happy and hopeful. (I'm hanging in there, don't you see in this process of elimination)
In the movie, during this scene, Hermione is heartbroken and Harry is also pretty sad, but they dance, in a way escape the reality of the war around them and their friend leaving to find some comfort and end up smiling. The adults are lulling them into an illusion to make them feel better (both in the song and in the movie (if you replace the adults by the radio)). However, the illusion doesn't last forever and when the song stops, they are back to reality and it's still horrible and sad. That's why Hermione stops smiling pretty fast, because she is back to reality. The illusion didn't make the war disappear.

The song in itself is pessimist: they can't do anything to avoid what's happening to them, and that's exactly the same in the movie. Adults can't save them, they can just send them a moment of peace, but in the end the children are truly alone and without any help. Just like the situation of Harry, Ron and Hermione during the entire movie. It just perfectly fits and completely emphasizes what they are feeling in this moment.
Having heard it earlier paying lesser attention, I had never realized how appropriate this song was for this moment. This song is very sophisticated and soulful. What do you think?!
