Regarding the whole John Lennon, 'Lucy in the Sky with Diamonds' thing.... I remember an interview in which Paul McCartney said they had tried drugs, but never had they written anything that sounded good while under the influence. When they did write music under the influence, it sounded amazing at the time, but when they played it back when they were sober they realized it was utter crap. And this is coming from Paul McCartney. He didn't deny ever doing drugs, but he did say that drugs weren't good for creativity. And given that I also remember John Lennon saying that 'Lucy in the Sky with Diamonds' was in fact written about his son, I wouldn't at all be suprised if his imagination was in fact that surreal (and that he had the ability to venture "into the heart of a child" as Bono would later write). It was a song inspired by a child, and he had the ability to be child-like in this sense.
