I finished this during an excellent long-weekend cricket tour of Amsterdam, without the benefit of the BRB, so I agree with the comments above, but especially those from Walterloo and borealis. No classic, but certainly enjoyable. Why does Philoctetes say that there is no symmetry? The grid has 180-degree symmetry, although the highlighting is not symmetrical. I too thought at first that it was what the celebrant is sometimes called (a deliberate red herring, I suspect) that had to be highlighted, rather than the celebrant's name, but it obviously has to be the latter. Looking back to this weekend 10 years ago, I see that there was no equivalent celebratory puzzle, so we need not necessarily have expected one this time. However, there was a related celebratory puzzle, which used the same shapely theme, about four and a half years ago, as midazolam points out.
Incidentally, I didn't entirely miss out on jubilee fever by going abroad. I watched the concert on Dutch television, which subtitled it in a way that demonstrated that the terrible jokes were all completely scripted well in advance. The Prince's speech, which outshone the performers' efforts by a long way, was also pre-released for subtitling.
IainGrace's first comment here reminds me of a story that Milton Shulman once told. He had been slagging off a particularly bad performance by an actress, whose husband happened to be listening. "Who are you to say that?" asked the husband. "Who do you have to be?" asked Shulman. Everyone can be a critic, and some are better at it than others; not everyone has the talent to be a composer.
