Butter commercials in the early 1980's were fairly routine affairs usually depicting a housewife and the preparation of a sandwich. That all ended when Aardman animated butterman Douglas came along in 1986.
Check out virtually all of his onscreen appearances (excepting the full versions of 3 of the veryrare Olympics 1992 series), right from the early musical numbers, through to the Penelope Keith narrated ones from the midnineties/early noughties.
The audio has been cleaned up where possible and there's even a couple of adverts here that you'll struggle to find elsewhere.
