Here's a pretty intense account of listening to King Crimson's debut album from writer Evan Brown and my thanks to Chris Taberham for sending a page from a Jethro Tull concert souvenir programme he purchased 40 years ago.

Chris says "This was the first concert I went to on September 25th 1969 at Newcastle's City Hall. The page with the face was really spooky but we didn't know what it was, or where it was from, as King Crimson's first album hadn't been released at that point.
I took the programme into school with me that week and loads of my mates started copying out the face in art lessons or on their school books. It wasn't until a few weeks later that we discovered which band the face belonged to."
