How dumb is this guy?

Ah you cought me, I was speaking out of context, and oh yes he recently decided to dice Pink Floyd by singing the chorus from all the brick in the wall's in reference to cellular walls, its not the reference the bothers me but the singing, it sounded like John Mccain was trying to sing it, and as I walked out the door with a Rush shirt on, he screamed at me, RUSH ROCKS(gave me a bit of a scare really), but what can I say, he is a teacher.

Let's face it — none of us in Pink Floyd are technically brilliant musicians, with great chops who can change rhythms, fifteen or sixteen bars here, there, and everywhere. And we're not terribly good at complicated chord structures. A lot of it is just very simple stuff dressed up." -David Gilmour
