But as usual with programmes of this length we had some oddities regarding intervals and start times. The opera started at 6.30pm and there was about 2 hours 45 minutes of music in 3 acts. So we could reasonably have expected there to be 2 intervals and the performance would have finished around 10pm, not too bad at all. Instead, there was 1 interval (after Act 1), leaving Acts 2 and 3 to be performed together, albeit with an extended pause between them. With a finish time of around 9.35pm. Most unsatisfactory, why do theatres shy away so much from 2 intervals in long 3 act operas.
