There was only one Chinheads advert made for McEwans Lager if I remember correctly.
The song was called Something So Real by Love Decree.
There was another advert where people pushed a huge ball up a hill and then smashed it through a big glass window.
That song was called You've Got The Power by Win.
Hipsway did the music to another advert using The Honeythief but I can't remember which advert it was for.
naw, there were definitely more, but the love decree answer is excellent. i also remember one with lines: "its a fact, its a fact, its a well known fact, that sometimes opposites do attract"
and there were at least 2 more, i'm sure...
