Mike Green also drew Weedy Willy for Oink! We collaborated on a strip for that comic once. Must dig it out one day. We exchanged letters a few times in the 1980s when we worked on Oink. IIRC comics were not his full time job. He produced ceramics as well I think, and ran a shop selling them in Cornwall or somewhere.
