The Last Night of the Proms came and went, and it was pretty much as anyone might have predicted, if they’d given it a moment’s thought. A sprinkling of popular classics, a pair of unthreatening premières, the familiar landmarks tastefully and affectionately done, and some show tunes and arias, sung by the soprano Golda Schultz with a generosity and warmth that couldn’t have been more potent if she really had been singing to a packed and cheering Royal Albert Hall, rather than TV cameras and emptiness.
