There is probably no place in Beverly Hills that says more about the fad-heavy Californian lifestyle than health food shop Erewhon — motto: ‘If it’s here it’s good for you’.
The Tonic & Juice bar on site offers a frankly bewildering list of concoctions, including coconut Bulgarian rose water and green juice with sun warrior plant protein.
And here, among the wannabes hoping to be spotted by a Hollywood producer over a ferociously overpriced glass of almond milk or a small brussels sprout salad (at £20) you will find all-organic vegan Richard Starkey, better known as Ringo Starr.
An unassuming figure, as slender as a teenager, he habitually wears all black and some jingly silver jewellery. As he wanders the aisles, it is hard to believe that he is 75.
He and wife Barbara — also enviably slim and glamorous at 68 — are regular visitors to the store and you can’t really miss them. Such is his fame that Ringo still causes a sensation when he appears in public.
Indeed, pictures of the former Beatle out in London with his son were published last week and it was remarked that Ringo looked younger and trimmer than Jason, who is 48.
He certainly looks decades younger than fellow surviving Beatle Paul McCartney, 73.
So how has Ringo done it? Well, his full head of suspiciously deep-brown hair gives him a youthful look, and the dark glasses he has worn continually, indoors and out, for around three decades also help.
Some suggest he has had a hair transplant, or a nip and tuck here or there. But the world’s richest drummer shrugs and says his secrets are simple. ‘Just working out and eating carrots,’ says Ringo.
A Pilates fan, he does indeed work out daily, and has been a vegetarian for years.
Ringo, who grew up in poverty in a tiny terraced house in Dingle, Liverpool, is so strict about his diet that he says broccoli is his main course, and won’t even have a slick of butter on his baked potato — he takes olive oil and brewer’s yeast instead.
He has embraced the Californian lifestyle, and it clearly suits him. But the real secret of his youthful glow is his happy marriage to Barbara Bach, and their mutual rescue from a hell of drink and drugs.
Ringo came with considerable demons and one failed marriage behind him — to fellow Liverpudlian Maureen Tigrett, which ended in 1975 — when he met Barbara, a model and actress.
A policeman’s daughter raised in Queens, New York, Barbara was divorced with two children.
