I lived in an area called Poets Corner.
It was about 15 minutes walk into town to the local comic shop.
So I would pop into the shop on my way into town.
It was a pretty well stocked - as good as Forbidden Planet used to be on Percy Street in the 90s.
One day, I was in there, browsing through a few books, when I felt a shadow behind me, and turned to face a huge (6' 3") hulking, hippy bloke.
He was dressed all in black with a silver Crow topped cane, and had huge silver rings on all of his fingers.
The 2 guys serving behind the counter went into 'Yeah, this happens every day' mode.
Yes, it was Alan Moore himself.
All I could say was 'Excuse me, mate' as I brushed past to get out of the shop.
Been kicking myself ever since that I didn't engage the man in conversation.
