If this video had been released today, it would be part of some bizarre "media strategy" to build up advance word about a new Bjork record.
But it's not. It's from 1994, when the only reason for a pop star to sit down and describe how a television set works was because the video was going to be used on an actual programme on an actual television station - and in those days there were only seven television stations in the enitre world (subs please check).
Can you imagine one of today's pop stars understanding the inner workings of a television? Does Aston out of JLS know the difference between 1080p and 720i on his HD flat screen? Can Dappy from N'Dubz make the subtitles work when he's watching Holby City or Dispatches? Have John and Edward established to their own satisfaction that televisions are not the same as magic mirrors?
