OBE
Corbett was a Labour Party campaigner, appeared in a party political broadcast, and was a guest of Harold Wilson. Harold Steptoe had been Labour Party secretary for Shepherd's Bush West in the sixth series episode, "Tea for Two". In 1969 Corbett appeared as Harold Steptoe in a Labour Party Political Broadcast, where Bob Mellish had to defend Harold Steptoe's accusation that all parties are the same. This was not in any way affiliated with Galton and Simpson who wrote Steptoe.
As Prime Minister, Wilson wished to have Corbett awarded an OBE, but the middle initial "H" was lost in the process and the award went to the Sooty puppeteer, Harry Corbett, instead. Both were eventually included in the same New Year's Honours list on 1 January 1976.
