I've known Steve for about 5 years. I've done writing for him and I have to say that he is one of the nicest guys in the business. I don't know how the fued between them got started, but I can't imagine Steve instigating it. He's not the type for petty bullshit. Brad on the other hand...well, my thoughts on him go back about 7 years and I won't go into it here. it's water under the bridge.
I wonder who shot the video. He's so avant-garde with his style.
