First Dmitri kindly took over when Rolando cancelled his 24 June Royal Opera House recital with Antonio Pappano.
Now the saviour of the day is sick himself. According to the latest Royal Opera House press release:
"Unfortunately Dmitri Hvorostovsky is now also under doctors' orders to completely rest his voice and it is with great regret that he has had to cancel all his current engagements."
(UPDATE - he apparently caught a severe throat infection during his recent Russian tour).
The good news is that the concert goes ahead - with three for the price of one! Joyce DiDonato, Joseph Calleja and Thomas Hampson have stepped into the breach, with ROH concert master Vasko Vassilev providing further support.
Statistics indicate that at least one of them should still be standing by Wednesday night.
