In 2015, he told Lincolnshire Life magazine: “The motivation of being a pop star or even being rich has gone, so now it’s seeing people enjoy themselves at shows but yes, I really enjoy my art.
“I still put my all into every show – doing less than that and you are cheating yourself and the audience but when I’m painting I’m truly at peace.”
