Back in the late 1990s, my right shoulder began to give me severe pain; I could only paint for very short periods of time, even with painkillers. 

I saw these beautiful trees as I was being driven out from Newry to visit my sister-in-law. When I returned home, I painted them from memory. I had to take my time, as I was using my left hand, and was amazed to find I could actually achieve something worthwhile - though very, very slowly. Eventually, the shoulder pain got so bad I had to go for a rotator cuff operation, which was very successful.

I was going to call it Recollections in Tranquillity, as a nod to the poet William Wordsworth, but my daughter Fiona suggested An Autumn Stroll, which seemed much more appropriate.
