Phantom of the Opera Recording

harpersbazaar.com:

In the fourth season of The Crown, there is a scene where Princess Diana (Emma Corrin) treats her husband, Prince Charles (Josh O'Connor), to an unexpected wedding anniversary present: a video of herself singing "All I Ask" from the musical The Phantom of the Opera.

The recording is no joke; she's dressed in an elaborate Christine Daaé costume on the actual set of the West End production with a full orchestra accompanying her.

Diana is proud of the feat, but Charles is not pleased by it. The late princess was known to be a huge fan of the musical and, according to some accounts, she really did give her hubby this gift.
