Agreed. I didn't mean to take a piss on our main man ;P He was essential to my childhood/adolescence too and I have no idea who'd I be without him or The Beatles. I think now, I have more affection for the Beatles than I do for John specifically, and less of an affection for the sixties as well as the things that came from it. The beauty in their sound is something that still stands alone though, and I hope for me it always does.
I feel silly saying I didn't know there was Beatles fanfic, but I know there is fanfic for *everything* lol.
