Alex Baldman in his "Shouts from the Stoop" blog includes two photos as evidence for his claim that Van Morrison looked like famous atheist Christopher Hitchins. (Although Christopher Hitchins' appearance was dramatically changed through his battle with a life-threatening illness. He succombed to cancer in December. Interestingly this leading light of the cause of atheism said in the latter months of his disease that any life after death "would be a bonus". Rather detracts from the atheist cause. Van's appearence, too, has been changed by several decades more of life and a few pounds extra in weight.)
Here's the evidence if you're interested in such foolishness.
