Here's the relevant bit:
But then I kept on getting crazier and crazier and Al had finally had enough of me. And when Al has enough of you, it's bad. He gave me three Valium and ordered me to take them and chill out. But I still had the rum. And the tour manager tried to take it from. He used to be in Echo and the Bunnymen. And he went to take the bottle from me and I broke it on his head. Blood was everywhere. I ended up passing out on their bus and when I finally woke up and walked to the front of the bus, the Echo and the Bunnymen guy with a big bandage on his head walked up. I asked him what happened. And he said, “You happened to me.” It was definitely one of top crazy nights I ever had.
Who was it?
