And his older cousin (not really, but still) Brett Anderson from Suede
And Matt Bellamy from Muse looks rather similar too (if you pick the right photo)
Moving from music to acting, I love Arthur Darvill (from Doctor Who and other things) and think he's a version of the Thin White Duke thing...
Obviously these guys don't look like twins or even brothers and some of them aren't fully English by birth, but do you see what I'm talking about? And (sigh) aren't they cute?
