It would be nice to have a classical concert , nothing heavy, Vaughan Williams, Chopin, Purcell perhaps, but I guess that wouldn't be popular so won't happen. Apart from the odd person, I've no idea who those performers named are, so couldn't say whether they're good, bad or indifferent. As for curtseying, if family members wish to bow and courtesy, that surely is up to them and nothing to do with anyone else. Members of the public certainly have that choice too. The coronation is definitely part of our history going back the first king of all England, Athelstan, who reigned 925 - 939 Every monarch except Edward Vth and Edward V111th have been crowned in Westminster Abbey. Jane Grey of course could be counted as uncrowned as well, but more often than not isn't. I think she should be as she was declared Queen ,but?? Other European monarchies do not have the long history of coronation,as mostly they didn't become one nation till many centuries later, and now don't exist.
