In August I undertook an unusual commission – to create a painting over the course of a summer evening event at ‘The Deck’ atop the National Theatre in London. The idea was to create a large ‘en plein air’ work showing a Thames panorama with partying figures in the foreground. I had visited the venue a couple of weeks ahead to work out the logistics, to make some preliminary sketches in thinking out the composition then on the evening of 20 August worked over a period of 4 hours creating this triptych.
