In June 2014, I was invited to the late Sir John Tavener’s Memorial Service in Westminster Abbey. It was a poignant occasion, marked by a number of special tributes and performances. My childhood idol Steven Isserlis performed Threnos during the service and as I made my way up to thank him for his moving performance, I was aware he was clutching a big blue score, and talking with Meurig Bowen, the Artistic Director of the Cheltenham Festival.

In seeking to understand the historic, divisive and to some bewildering Brexit vote, I will turn to theatre. Through my regular exposure to it, I can number among my ever-widening acquaintance a young king, a whistleblower, a minimum-wage movie usher, a recovering alcoholic, a passionate teacher, a grieving parent, a struggling miner, an evangelical preacher, an underpaid social worker, a dementia sufferer, and a pair of star-crossed lovers.

After a grey start, there was a spectacular sunset around midnight on the second of my two days in Reykjavik. It's what brings one of Iceland's most brilliant younger-generation talents, pianist Víkingur Ólafsson (and yes, he's worked with Björk), back to his homeland every June. He launched Reykjavík Midsummer Music in 2012, the first full year of programming at Olafur Eliasson's ever amazing Harpa concert halls and conference centre on the harbour.

In the opening scene of Boys Will Be Boys, the lead character, Astrid, talks about how there’s a boys’ world and a girls’ world. Boys’ world is where you want to be. That’s where power is, that’s where fun is. Boys get to be boys and that means holding all the cards, and doing whatever the fuck you want. How do women get into boys’ world when they’ve got a vagina?

Even without any particular pomp or focus for celebration, the 70th Edinburgh International Film Festival has felt like a particularly strong and broad-ranging one, with a programme so big it was a struggle to take it all in.

The Edinburgh film Festival’s signature prize, named after one of its most celebrated directors, is the Michael Powell Award for best British feature film. The dozen up for the award this year have included a Scottish love-triangle road movie, a dystopian drama, an adaptation of Macbeth, and a Welsh language thriller involving identical twins. Where once British film was a predictable affair, rooted in costume drama and social realism, it appears to be happily diverse at present.

It’s a little over two years since I was approached to adapt The Mighty Walzer by Howard Jacobson for Manchester Royal Exchange. I was living in Liverpool at the time and had recently seen That Day We Sang by Victoria Wood at the Exchange. It was terrific, wonderfully directed by Sarah Frankcom. I had never seen a musical in the round before, it was so dynamic. There’s nowhere to hide in the round, you can’t get away with anything, you’re totally exposed, and I remember thinking how great it would be to write for such a space.

The Holland Festival is one of the greats. It has a British director, the articulate Ruth Mackenzie, formerly of the Chichester Festival and the cultural Olympiad, now into her second year. It’s the same age as Edinburgh and Avignon – 70 in 2017 – but not as well known, though it should be. “We must,” Mackenzie says, “seriously punch above our weight. And we do.” The festival was founded after the Second World War on, comparable to the Scottish and French ones, principles of reconciliation and presenting the best productions of the human spirt.

To anyone who says that you can’t make a great film about golf, a film which is funny, sexy, and rousing, I have just two words; sadly, for those who attended the opening night of the Edinburgh Film Festival this week, those words are Tin Cup.

When I sang Isolde to Alberto’s Tristan at English National Opera all those years ago, it was a joy to hear such wonderful tenor sounds in my ears, my heart and my soul. It was always difficult for him to memorise his work and up until the first night I wasn’t quite sure what was going to happen. Yet when we went into that other place of performing he became Tristan and we travelled, on the waves of his beautiful sounds, to places I have seldom been.
