Thom Yorke was recently interviewed for a new film entitled "Eat This!" which is a documentary about the ethics of eating meat, and it appears that good old Mozzer was how it all started. When asked what led him to stop eating meat, Thom replied:

"A list of things I guess. First thing was Meat is Murder, The Smiths. The second thing was getting sick all the time every time I ate meat -just getting sick a lot and the third thing was I started going out with this girl and I wanted to impress her so I pretended I'd been vegetarian all along and I immediately felt a lot better, a lot healthier. I was concerned, as many people are, about that you're not going to get all the things you need in your diet, you're going to get sick all the time, but the exact opposite happened to me, so I never looked back, it was never a problem straight off."
