Aceana
His hair looked cool in the bar.
I've always personally said that his hair in that scene and those flashbacks looked like Billy Idol, which makes sense, I guess, if he was in an 80s rock band...still. Not necessarily a bad thing, I've just taken to calling it that.
As for his hair long or short, I've always liked it long. It's so fluffy and nice looking and I don't mind it short now that I've gotten used to it but I still prefer it long.
The song itself is definitely one of my favourites and when I'm home alone I just blast it and belt it along with him. I think for 'One Song Glory' not being his 'One Song Glory' it was more like one of those musical things where they're singing they're feelings...so in all actuality the character didn't actually write the song he was just...singing because it was a musical instead of like a normal movie where it would be expressed in dialogue or something else. That's my personal opinion, anyway, and then 'Your Eyes' was the song the character actually wrote. Anyway, enough blathering for me.
