The McGregor Brothers were introduced in Coronation Street as old friends of Eddie Yates. They showed up for his stag night.
The jokes was that one was white the other was black. They were half brothers and in Coronation Street at the time, a black person was a rare sighting.
A few years later they had their own spin off series as The Brothers McGregor. They were also played by different actors.
The first episode introduces the brothers as dodgy second hand car salesmen. Wesley (Paul Barber) sees himself as a prominent black businessman.
Cyril (Philip Whitchurch) is a part time bouncer and sees himself as a nightclub entertainer. He also is in a relationship with Glenys but holds off marriage by repeatedly stating that he is waiting for his divorce to come through.
A mildly amusing first episode. Cyril unwittingly finds himself to be a getaway driver as the club he works for is robbed.
There seems to be 3 main settings for the show. The car lot, their mum's house and the nightclub.
It was notable that one of the youths interested in buying the car was Ian Hart who became famous as Professor Quirrell.
