The same year, he took part in the BBC's The Young Ones, in which six celebrities in their seventies and eighties attempted to overcome some of the problems of ageing by harking back to the 1970s.
On 14 December that year, he guested on the ITV panel show, Loose Women, to announce and celebrate his recent 88th birthday.
