There are various sorts of knighthoods. Today the distinctions are blurred because of general ignorence of the distinctions and because the recipients are simply referred to as "Sir" in the press and other media. It's my belief that entertainers should be given another title..whether Jagger or Olivier. Knighting people on economic grounds is getting pretty low and people mentioned like Jagger and Rotten, whose lives are the worst examples of how ordinary people (forget the examples like Amin, Sharon, Bush and similar) should live their lives. In my opinion they denigrate the concept of knighthood. Perhaps a title like "Eco-asset" would be a better title and use the simple Mister when applied. Thus "Mr Mike Jagger, Eco-asset by appointment". In dragging the concepts of royalty and chivalary...the latter term completely foreign to rock artists in general...increasingly into the gutter the British parliament, and the queen (in this case) who 'agrees'to the Prime Minister's suggestions usually, is simply bringing all the good things of British Aristocratic Service, Military Service, Diplomatic, Charitable and other Service into less than mediocrity and no longer an example for the young and not so young to follow. I accept that many other knights have also been knighted after less than desirable example for us to follow. . Was, for example the appalling Robert Maxwell a knight? However when one gets to the level of knighting Jagger..who has been quite a businessman, Rotten and others I think its all over red rover! Knighthood was about reaward for a noble life and as an example to be followed.
