There's a great song about this - spoken word musical track really - by the Scottish band, Looper. I'm sure I can't do it justice off the top of my head, but here goes.

It's called 'Dave The Moon Man.' The narrator met Dave The Moon Man at a party, where he was giving short lectures to anyone who would listen, about all this stuff he'd found on the internet - about the Van Allen belt, how if they had made it through it the radiation would have killed them shortly afterwards, and about how the light sources were all wrong - it suggested studio lighting...

'There was a whole lot of this, and a whole lot more besides. I thought he was on a mission, Dave The Moon Man, to convince everyone there had never been a moon trip. But I was very wrong. That wasn't it at all. He was telling everyone these things in the hopes that someone would prove him wrong... he wanted someone to convince him that they really had been to the moon, in that rocket that looked like it was made of tin-foil and cardboard, which nowadays you probably wouldn't even trust to get you down to the shops... Because it was so much harder otherwise, finding the will to get things done, drunk, lying on the lawn... because someone had done that, and nothing was more impossible than that...'

It's a shame the words don't seem to be on the internet anywhere...
