Marcin Wicha’s mother Joanna never talked about her death. A Jewish counsellor based in an office built on top of the rubble of the Warsaw Ghetto, her days were consumed by work and her passion for shopping. Only once did she refer to her passing, waving her hand around her apartment and asking Wicha: “What are you going to do with all this?”

There’s a lot of going back to the future in theatres just now - shows (like this one) postponed by 18 months or so and delayed still further by co-star Roger Bart being indisposed on press night are bringing the bright lights back to the West End.

The Wigmore Hall is a bastion of white musicians playing the music of white composers to a largely white audience and it is to the credit of the management that, in seeking to diversify, it staged this lecture-recital on the history of black musicals in Britain from 1900-1950 in a main evening slot.

How would you solve the problems inherent in a production of Malcolm Arnold’s The Dancing Master, bearing in mind the need for social distancing for performers, comparatively miniscule budgets for scenery and props, and the uncertainty surrounding just about everything in a summer opera festival these days?

The City of Birmingham Symphony Orchestra believes that its current post-lockdown summer series features the largest orchestra currently performing live in the UK. It’s not an easy claim to verify, and the full string section certainly wasn’t on stage for this matinee performance under the orchestra’s associate conductor Michael Seal.

In May 1981, a new-minted music graduate newly embarked on a career in journalism, I was pleased as punch to secure a commission from Capital Radio. Forever Young: Dylan at 40 was broadcast on 24 May. I’ve a tape of it somewhere, this 30-minute programme voiced by a guy more suited to Carlsberg ads. The script – written using a golf-ball typewriter, music cues in its wide margins, hints of Tippex here and there – turned up a couple of weeks ago as I tidied my study.

Some production concepts seem so obvious, in retrospect, that you wonder why they haven’t been tried more often. Traffic hums in the foreground in the opening shots of Grange Park Opera’s new film of Ravel’s L’heure espagnole, the passing cars reflected in the window of an antique clock dealer’s store. Ticking fills the soundtrack as we dive inside, like Mr Benn entering his magical shop; at the same time, the piano sounds Ravel’s perfumed opening chords. Reality or fiction? Opera or documentary?

“This book is a journey of historical discovery, set out sequentially in order to convey a sense of what has changed over time.” Add to this sentence, the title of the work from which it is taken, The Art Museum in Modern Times, and you’ll probably have a reasonable sense of Charles Saumarez Smith’s latest book. Simple, effective – Smith presents us with a series of case studies of museums, placed in chronological order according to each’s unveiling.

Sir Mark Elder and the Hallé are back in the Bridgewater Hall for the first programme in the second tranche of the orchestra’s digital Winter Season – filming that had to be postponed from its original planned date but is triumphantly achieved now. As before, the full orchestra is accommodated with a monster extension of the platform to allow for adequate distancing.

Trilogies (it is noted, in the term’s Wikipedia entry) “are common in speculative fiction”. They are found in those works with elements “non-existent in reality”, which cover various themes “in the context of the supernatural, futuristic, and many other imaginative topics”. All of these apply in some sense to The Things We’ve Seen, the latest novel from Spanish writer Agustín Fernández Mallo.
