Co-Op Live, Manchester
The 75-year-old is in ageless voice and playful mood throughout a performance of as many of his greatest hits as can fit back-to-back in two and a half hours

The concert is just minutes old when the crowd recognise the tell-tale first four notes of Stevie Wonder’s 1980 Bob Marley eulogy Master Blaster (Jammin’), and instantaneously rise to their feet in unison and pure joy. For almost two and a half hours, the soul-funk-pop legend rifles through his back catalogue with the glee of a small child deciding which toy to play with next. At various turns he’s peacemaker – encouraging world leaders to “lead us to a better place” – then 1960s soul man, balladeer, funkmeister and synthesiser soul explorer. Such are Wonder’s musical treasures that the 26-song setlist can pile through Higher Ground’s glorious elasticated groove in the first four numbers and omit Uptight, Happy Birthday, He’s Misstra Know It All and many other classics altogether.

This rare UK visit finds the 75-year-old legend in ageless voice and playful mood. Blind since shortly after birth, he swaps sunglasses and jokes “I can’t see without my glasses”, then leads the crowd into an impromptu burst of You Are My Sunshine by way of intro to You Are the Sunshine of My Life. Given his age and the length of the show, it’s understandable that he takes a break. There is a slight lull as backing vocalists take the spotlight, and later his son Mandla Morris sings I Can Only Be Me.

Older gen Zers, with memories of the 2009-10 financial crisis, are saving more, but experts say employers should help

Research published at the end of last year by the Investment Company Institute with help from the University of Chicago found that gen Z – those born between 1997 and 2012 – are “outpacing” earlier generations in contributing to retirement, having more than three times more assets in their 401(k) retirement savings accounts than gen X households had at the same time in 1989, adjusted for inflation.

This mirrors a 2023 study from the TransAmerica Center for Retirement Studies, which found that gen Z is doing a “remarkable job” saving for retirement with many putting away as much as 20% of their income towards the future.

Artwork and poems from contemporary artists and former Bethlem hospital patients to go on show

The vivid dream that vanishes on waking but fragments of which remain tantalisingly out of reach all day. Powerful emotions – tears, terror, ecstasy, despair – caused not by real events, but by the brain’s activity between sleeping and waking.

Dreams and nightmares have long been studied by psychologists. Now they are the subject of a new exhibition featuring several artists that were patients at the world’s oldest psychiatric hospital, Bethlem (sometimes known as Bedlam), and its sister institution, the Maudsley hospital.

This mid-priced bed-in-a-box mattress went from rock-solid to soft in weeks. Here’s what impressed me – and what could be better

• The best mattresses: sleep better with our six rigorously tested picks

I fear the Panda Hybrid Bamboo is playing games with me. When I first tried this mattress last year, it was among the firmest of all contenders in my mission to discover the best mattress. It was great-looking, easy to handle, and firm. Several months later, it’s great-looking, easy to handle, and … soft?

Not quite. But Panda’s mattress is a fine example of what happens to memory foam after you’ve slept on it for a few months. The initially solid sleeping surface adapts to your body, becoming softer and cosier. My tests with weights reassured me that the mattress was still supportive and not sagging, but it definitely wasn’t as firm as in those early weeks.

Fat Boy Slim is on the wheels of steel. Can he be overheard over the engines? Right here, right now, it’s still raining. “I love that it’s raining,” says Lewis Hamilton. “Good old English weather. I get nervous as this is the week you get nervous the most. The fans have been ride or die with me. Thanks to them I really get to enjoy it.”

It’s raining in Northamptonshire. Good news for Max? Wet weather doesn’t usually stop him. A prep race was abandoned earlier in the day but the track dries quickly.
