May was approached by producer Tony Shryane to join The Archers as Nelson in 1952. May remained with the show until he was forced to leave in January 1997 due to his declining health. He died later that year.
Listeners voted Nelson the "greatest rogue" in Archers history, while a writer for SOAP magazine named him one of the "10 Great Archers Characters". They said, "Son of the late, lamented Walter Gabriel whose eloquence and erudition cloak a shady past involving criminal activity and a suspicious absence of any love interest anywhere along the way, though he mysteriously acquired a daughter somewhere down the line."
