Eurovision Call: Jason and Chelcee’s Ultimate Guide****

Andrew: The Problem Prince **

Prepare to feel 13 percent better. According to social scientists at Imperial College London, countries taking part in the Eurovision Song Contest enjoy a measurable mood boost for days, even if they finish last.

For the UK this year, 13 percent sounds like a serious underestimation. With a week-long run-up to Eurovision on Saturday, culminating in the mega-budget party in Liverpool, we should be walking on sunshine.

Add to that national euphoria in the aftermath of the coronation and Britain could very soon be the happiest country in the world. Eurovision spirit reaches parts and people are mostly unaware of the joys of the event. Comedian Jason Manford admitted in Eurovision Calling: Jason And Chelcee’s Ultimate Guide (BBC1) that before launching the show last year he had never heard Sam Ryder’s entry Space Man.

But he has now succumbed to the addictive optimism of the competition. By the end of the hour, he was on stage at a gay pub in Manchester, singing Conchita Wurst’s Rise Like A Phoenix, the 2014 winning national anthem.

The Eurovision Song Contest gives everyone a permit to camp for the night. Sequins and feather boas are optional, but if they make you feel 13 percent better, why not? You might assume it started with Abba, and the neon jumpsuits Anni-Frid and Agnetha wore for Waterloo in 1974. Cliff Richard. Our eternal bachelor wore a ruffle-front suit worthy of Austin Powers.

This year we are represented by Mae Muller, with a cynical formula number called I Wrote A Song. Jason chatted to her over a pot of tea, though he didn’t ask the Corbynista singer any awkward questions, such as: “You posted on Twitter that you “hate this country” – don’t you think it’s hypocritical to represent us in the Eurovision Song Contest? ‘

Mae has said before that it’s crucial she does the contest because “a lot of young women follow me and it’s important that they can see that they can have a voice.”

Unfortunately, she doesn’t have much of a voice herself – it’s thin and a bit nasal, not the kind of floating, theatrical sound that traditionally works well in the Eurovision Song Contest. This year’s winner is more likely Sweden’s Loreen, who triumphed in 2012 with Euphoria. But even she could compete against Ukraine’s entry, Heart Of Steel by Torchii. Public backing could well mean that Ukraine rivals Ireland, Israel, Luxembourg and Spain in winning two years on the trot.

We can be sure of one thing. In the Kremlin, no one dares to flaunt sequins and boas with feathers.

Emily Maitlis didn’t go that far in celebrating her Newsnight interview with Prince Andrew, ending his career as a working royal. But there was a strong note of glee over the second part of Andrew: The Problem Prince (Ch4). Faint reconstructions showed Emily arriving at Buckingham Palace, clutching a shoulder bag of clean clothes and her notes. The brand logo on the bag was Sweaty Betty – a sarcastic reference to the prince’s claim that an adrenaline overdose during the Falklands War left him unable to sweat.

Pictured: Emily Maitlis who will appear in a new Channel 4 documentary about her BBC Newsnight interview with the Duke Of York. The journalist, who grilled Andrew about his relationship with pedophile financier Jeffrey Epstein, is executive producing a new documentary, part of the broadcaster’s programming surrounding the coronation.

Remarkably, she said that he had already told her about his perspiration deficiency during conversations prior to the interview.

After filming was done, he invited her to film with him. Thursdays are apparently cinema nights at the palace. Emily made her excuses and left.
