The Royal Box, which seats approximately 80 people at the south end of Centre Court, is reserved each day for members of the Royal Family and a host of illustrious guests invited by the Club Chair Deborah Jevans.

Day 3 of The Championships was graced with a visit by Her Royal Highness Princess Michael of Kent, accompanied by the acclaimed Swiss interior designer Christophe Gollut, who cast an expert eye on the business of decorating the intense emerald-green floor of Centre Court with lines of ultra-vis yellow (the trajectory of flying balls) and splashes of white (the scurrying players).

Aryna Sabalenka was first out to pepper the canvas with her brutalist style of artistry against the Czech world No.48 Marie Bouzkova. If she were looking for an anthem for her combative style, Dave Grohl, founder and lead singer of the rock band Foo Fighters, was on hand to oblige.

And if it went, well, Mamma Mia! Here We Go Again… there was Dominic Cooper of Abba-inspired film fame.

On the eve of the tournament, Novak Djokovic had joked that Sabalenka lacked intensity. But up in the eyrie of the Royal Box was a charismatic athletic performer who far outguns the No.1 seed in that respect. Stand up – but please don’t segue into a trademark Five Knuckle Shuffle – John Cena, the powerhouse Undisputed World Wrestling Entertainment (WWE) Champion.

Fans rave about the arsenal of manoeuvres Cena takes into the ring – the diving elbow drop or crossbody and so on – an area of expertise on which his fellow guest, Olympian Tom Daley, might have plenty to say.

Eagle-eyed viewers noted that Daley did not bring along his knitting, as can be his wont. Just as well, given the special-edition box of meltingly delicious artisan chocolates Royal Box guests find on their seat (Amazonian Truffle Dark Chocolate and Salted Caramel, adorned with The Championships logo in gold, wrapped in Club purple tissue paper, inside an ivy-decorated box).

Centre Court is immune to rain preventing play, so the sight on the big screens around the Grounds of Daley and fellow gold medallist, the Paralympic swimming star William Ellard, cast a positive light on the passing aquatic conditions.

Uplifting, too, was the presence of England football manager Thomas Tuchel, the former Chelsea and Bayern Munich boss who wants his charges to “play with a smile”. (No doubt he had plenty to chat about with Roy Hodgson, a predecessor in the Three Lions hot seat who most recently managed Crystal Palace, just down the road from Wimbledon.)

And the comedy power couple of Leslie Mann and Judd Apatow, whose respective film and TV oeuvres boast titles familiar to tennis: Love, Knocked Up, The Return…

After the entrée, the schedule served up two tantalising Battling Brit matches for the home crowd to savour: Oliver “I’m a little bit too loud” Tarvet seeking to make nothing of the 732 world ranking places between him and Carlos Alcaraz, and Emma Raducanu facing the 2023 Ladies’ Singles Champion Marketa Vondrousova.

With classic All England Club attention to detail, young Tarvet was treated to a decibel-hardened Royal Box audience in Grohl, Cena (the WWE star turned actor has also released a rap album), Tom Chaplin of the British band Keane, Glastonbury headliner Olivia Rodrigo and singer Nick Jonas.

Jonas and his brothers were stars of the Disney Channel. In the unpredictable world of first strike, grass court tennis, players can find themselves in a Wonderful World of happy endings. Both Raducanu and Vondrousova have scripted fairytales for themselves as surprise Grand Slam champions in recent years.

The British No.1 says she’s set on "embracing the occasion, feeling the surroundings and the atmosphere". It doesn’t get better than playing in the cauldron of Centre Court Wimbledon in front of a sports and entertainments star-packed Royal Box.
