Somebody in another thread mentioned the live performances of Drama Queen in 2009, and it just occurred to me that I've never actually watched it all the way through before. So I've just watched it now, and omg, I can't believe what I've been missing. Drama Queen is by no means my favourite song (it's not even one of my faves from the trilogy), but that performance is so beautiful. I love his voice so much, it's so soothing. I also love the close-up of his hand at 1:17, you can see that he has only one fingernail painted blue. LNOE sounds wonderful too - his voice is the perfect mix of beautiful and sexy on that one.
I'm not usually a huge fan of acoustic songs, but watching Billie's acoustic performances is absolutely magical.
