7 July 02009 was Minimum Labyrinth's birthday, when we first performed 'Align', an illuminated talk with music about the history of ley lines and London psychogeography. It was in a room at the top of the George Inn, Southwark, and in the room directly below that, 15 years later, I first came along to a Long Now London meet-up. And this led to a new guided walk, 'By A Long Chalk', written specially to accompany and celebrate Longplayer Live at the Roundhouse, Camden, on 5 April 02025. I have used the money the walk raised to buy this day of Longplayer as a small birthday present for ourselves!
