The first 50 minutes are up (I said earlier that the conductors each get 40 minutes per session, but it is in fact 50), and it is the Czech Jiri Rozen who has finished his first turn.
A nice moment: after rehearsing a passage he drops his hands and says a big thankyou. The orchestra give him a clap and tap a few bows on stands, and give him a smile that must surely encourage him. But, ha ha, he’s not going anywhere just yet! He still has 5 minutes of his time left.
