Only funerals of national leaders and statesmen/women are televised . Funerals are for the family and close relatives to remember the deceased in private.
No doubt there will be news coverage of the funeral but NOT the funeral itself.
Princess Diana was a senior member of the Royal Family and would have become Queen until Camila got in the way!!
Just a bit more important than a pop singer!
You also have to remember that there was also a very unsavory side to George Michael, including conviction for a 'lewd act' in a public toilet!
That casts a shadow over his life.
