" Time often is forgiving and dismissive of the influences, because they recede. We look at Sgt. Pepper and we go "wow! How did they ever think that up?" but of course, if you got into Paul McCartney's bedroom, found his record collection at the time, you would find out. But the clues are gone. It's like evolution: there are certain pure situations that hang around longer, but the ones that got them there don't have time to leave fossils. We have a giraffe, we have a horse. But where's the horse with the long neck? The link species disappear. "
