What ought to have concerned Wenger was the thousands of empty seats at the Emirates and the flatness of the occasion and the performance.
According to Pritchard, however, "there is absolutely no doubt" that this is Montreux in Switzerland, that the year was 1928, the month June, and the occasion of the performance the town's annual festival, La Fête des Narcisses.
Mrs. Obama herself spoke charmingly on the same stage, perfectly fitting her words and tone to an enthusiastic occasion: the first performance in a planned dance series, matching performances in music, poetry and other arts that the Obamas have already hosted at the White House.
So one movement was dropped for this occasion, the only performance of the work this season.

The Dutchman won the European Cup with PSV Eindhoven in 1988 but his last Champions League game was Chelsea's infamous 2009 semi-final against Barcelona, an occasion overshadowed by the performance of the Norwegian official, Tom Henning Ovrebo, who turned down a succession of penalty appeals for the hosts before Andrés Iniesta secured Barça's progress with a last-minute equaliser.
The bigger the occasion, the bigger the performance.
And plastic biohazard bags for those occasions when the performances were not up to snuff.
