Wouldn't have been particularly contentious back in the day mind with the likes of the two Ronnies similarly 'made up' on prime time saturday tv.
I bought the 12" single when it came out in '83, it took me a minute to work out how to play it though as the run in groove just didn't seem to be taking the needle. I soon sussed it, the needle needed to be dropped on the inside 'run out' groove as the record played outwards/backwards... Genius!
