As I said, Roger used to be a slapped ass, and now he looks like a classy old guy. David used to look good (maybe a bit fishy :P) and now he looks like - as my brother said - a bulldog. It's rather funny to see how people's faces develop.
By the way, I always found one "image" in Roger's Berlin concert to be really interesting. If you look here ( http://www.youtube.com/watch?v=gZ2tluarzZs ), at the 3:26-3:30 part, Roger's face looks really similar to what he looked like when he was younger. Put that face next to him doing Carefur With That Axe, Eugene in Pompeii, and you'll barely see a difference. Thought I'd share. :)
