He is conditioned that way. A few years back Radiohead was touring and they played at a venue I work at in Atlanta. We helped unload stuff from their touring bus, and all that jazz. Weird thing is, we wheeled in a large case shaped like a horn. I thought it was strange, since I didn't remember any horns on Radiohead songs. Anyways, we stayed back while their people set up the stage and all that. Thom, Jonny, Ed, and Phil came in to do a soundcheck, and Thom goes over to the large horn case, which was still unopened, and kicks it. It starts to rumble and the latches then unlatch and the case opens. There was Colin, completely naked except for a saddle on his back and little hooves tied tightly to his hands and feet like a Chinese woman. Thom taps the floor twice with the heal of his boot and Colin rushes out on all fours. I could see tears in his eyes as Thom then mounts his saddle and starts yelling 'Yaw!' I looked over at Jonny, and he was turned away, trying not to look. Colin is now galloping all around the stage while Thom was singing parts from Lotus Flower. Ed was near me, so I turned to him and asked, 'What's going on? How can you let this happen to Colin?' Ed shrugged and says, 'It was either me or Colin, what can I do?' I continued to stare in disbelief at the spectacle before me. After a while, Colin seemed to be slowing down from running, and Thom turned red and was shouting at Colin to run faster. Eventually Colin just collapses and Thom slides off and starts having a tantrum on the floor. Some of their assistants pick him up and bring him backstage. Colin curled himself back into the case and shut it, then the other band members proceeded with the soundcheck like nothing happened. I really hope they don't come back.
