This​ was a 42-year marriage of convenience between forgiving but frequently exasperated business partners and poetry rivals. It was launched with a seize-the-day telegram, after a one-night, earth-shuddering, world-tilting performance in a jazzed-up garage. Before moving on to occasional meetings and decades of dutiful, near conjugal correspondence from all parts of the globe. Before...

Not many guests arrive at Shangri-La, the cloud-shrouded lamasery/hotel that occupies the paying mid-section (levels 35-52) of the London Bridge intervention known as the Shard, by way of a 149 bus out of Haggerston. This on the day of a seasonal Underground strike that has to be explained to bemused knots of grounded tourists as they squeeze through a complexity of automated barriers, encumbered by caravans of luggage.

They dig and the earth is sweet. The Hackney Hole is eight square metres, straight down through the lawn of a decommissioned rectory. This secret garden is separated from St Augustine’s Tower by a high wall of darkly weathered brick.

While trying to ignore my seventieth birthday I was offered an unexpected gift, which was also a challenge: the chance to nominate seventy films that would be shown in orthodox and unorthodox venues across London. I didn’t want to play the listing game of best or worst or personal favourite. And it didn’t work, in Dillinger fashion, to isolate one film for every year of my life; the big clusters came in the 1960s and there were plenty of desert epochs during which I saw practically nothing. I scanned my published books, in reverse order, and assembled a catalogue of films referenced. I wrote brief notes on all of them, realising that there were unexpected connections and overlaps.

Silent, heavy doors open on a line of dense and minatory charcoal drawings, linked like coal trucks, and arranged on the floor in a provisional order – I visited before the all-encompassing Leon Kossoff show, London Landscapes, opened last month (it closes on 6 July). Tolerated afternoon light insinuated from a west-facing window, to be swallowed in that privileged and subtle...
