Trying to identify weird 90's UK butter ad.

Ive mentioned this elsewhere to no avail. Wonder if this rings a bell with anyone? TV commercial for butter or spread which aired circa between 97-99. It might have been for Utterly Butterly or I Can't Believe It's Not Butter. The ad seemed to be inspired by Monty Python TV series with shades of the Goodies plus an element of grindhouse movie in particular Texas Chainsaw Massacre. It was deliberately shot to look like it dated from the 70s with slightly washed out colour and retro fashions on the actors. There were short fake continuity links like the ones on Python, these had a guy who looked like Graham Garden circa 1970 outdoors holding a microphone and he had a Scottish accent. One line of his i remember was "well, good news".

It ended with this attractive blond woman in a mini skirt and 60's style knee high boots ironing in a kitchen and smiling inanely at the camera. We see a big hole being cut in the door by a chainsaw from outside and this small gibbering guy in goggles comes through it and points at the woman. A larger guy comes through the hole and pushes him out of the way then glares around the room. It then cuts to the woman's reaction shot. There's a freeze frame on her face and she does this exaggerated look of shock with her hands up to her face.
