Keith Richards talks tax policy with Rolling Stone:

The Stones are famously tax-averse. I broach the subject with Keith in Camp X-Ray, as he calls his backstage lair. There is incense in the air and Ronnie Wood drifts in and out–it is, in other words, a perfect venue for such a discussion. "The whole business thing is predicated a lot on the tax laws," says Keith, Marlboro in one hand, vodka and juice in the other. "It's why we rehearse in Canada and not in the U.S. A lot of our astute moves have been basically keeping up with tax laws, where to go, where not to put it. Whether to sit on it or not. We left England because we'd be paying 98 cents on the dollar. We left, and they lost out. No taxes at all."
