Tucked behind buildings, encircled by busy roads in the borough of Hackney in London, there's Abney Park. It's one of the 'Magnificent Seven' cemeteries of London with marble-topped tombs half hidden by vines. It is a designated nature reserve protecting a rich ecological environment. Locals nip in, to take their dogs for a walk, to clear their heads and to get lost on its winding paths. It's home too for a rich variety of birds, including green parrots. Planted as an exotic arboretum in 1840, there are around 200 trees, some still remain from that first planting. It's a mild October day, and the rain is falling. Everything is being drenched. After a long time walking under dripping canopy we find a spot for the microphones. Set back from the path it's a small leafy hollow, bisected by a diagonal spur growing out of an old oak. The rain is falling heavier now, sifting down in waves down through the branches, pattering onto millions of waxy leaves. These old trees are bathing in it. They're pushing away the noise of the city, and sheltering the tranquillity of Abney Park under their boughs.
