It's not often that a group of performers has a very interesting selection of noses. Normally it's the frocks that catch your eye (although they do here too), or it's that especially eye-catching backdrop. Whatever it is, in these days of televoting, if you can add anything to your stage performance to eke an extra point or two out of things, you're on a winner.
Today's random song did have a lot of things that made it stand out from the crowd. Outfits that were retina-detaching rather than eye-catching. A feast for the nasal fetishist. And a brickwall. Brilliant.
