Sorry. Too late.
This is from yesterday's live stream.
Kids, it doesn't get better than this. There is a film to accompany this where both stars are interviewed, Netrebko in English and Kasarova in German, where Kasarova talks about how important it is to sing with the other person. It is a revelation to see this interview.
The production appears to be all about Netrebko's legs.
I'm on Radio 3 In Tune today
