Following the death of Queen Elizabeth II, the Royal Opera House and BBC Proms have canceled performances.

The Royal Opera closed on Sept. 8 and canceled performances of “Don Giovanni” and the Aida Insight. The house said it would contact ticket holders for refunds or to change to another performance.

Meanwhile, BBC Proms canceled two nights including the Last Night at Proms. The festival said, “Following the very sad news of the death of Her Majesty The Queen, as a mark of respect we will not be going ahead with Prom 71 on Sept. 9, or the Last Night of the Proms on Sept. 10.”

“Don Giovanni” is now set to open on Sept. 13 and the Royal Opera House is set to open its production of “Salome” on Friday, Sept. 9. Meanwhile BBC Proms was set to feature Lise Davidsen on the Last Night at Proms.
