One of YouTube seems to be The Shirelles version with the caption at the end "Contact Your Coal Merchant" 
The Independent Broadcasting Authority (IBA) had a ruling until 1991 (I think) when it was replaced with the Independent Television Commission (ITC) that commercial advertising could not use licensed music (pop songs). So I think the cover version would have been before 1991 and The Shirelles version on or after 1991. When I saw this I thought you meant The Coallite advert!
