I knew it was too good to be true.
This is the sicknote email I just received:
Dear patron,
We are sorry to announce that Anna Netrebko is suffering from influenza and has today withdrawn from the concert at the Royal Festival Hall on Tuesday 19 May 2009. At such short notice, it has not been possible to offer an alternative programme with Dmitri Hvorostovsky, the Philharmonia Orchestra and Ion Marin, and so regretfully, the performance tomorrow will not take place. We are working to identify an alternative date for the concert in the future months.
Aaaaargh!!!
