The final section of The Joy of Disco illustrated how disco music grew into a vast global phenomenon. It had been brought to the popular mainstream by the success of Saturday Night Fever, was enjoyed by grannies at Pontins, and even prompted 70-something showbiz veteran Ethel Merman to make a disco album.

My most rock’n’roll moment of the last year was probably travelling 120 miles an hour on the wrong side of the road in a black Mercedes as part of Prince’s police convoy on the way out of Lisbon to the Super-Rock Festival where the diminutive star was headlining. The traffic was completely jammed on the way to the concert and it was the only way to get there on time. In the convoy also were Tim Ries, The Rolling Stones’ regular sax player, and Ana Moura - Prince’s most recent protégé and Portugal’s latest and most celebrated young fado singer.

Mick Jagger is heading up a band named SuperHeavy. Also in on the project are Joss Stone, AR Rahman (composer of the Slumdog Millionaire soundtrack), Dave Stewart (the former Eurythmic) and Damian Marley. It seems outlandish and the product of an overheated PR person’s imagination, but many things in life can be both. Yet, this is real, not an April Fool-type joke.

Last weekend ballerina Tamara Rojo performed to the largest live audience ever to watch the Royal Ballet, at London's O2 Arena. But what was it like facing 12,000 people, and trying with her partner, the Cuban star Carlos Acosta, to tell the intimate story of two young lovers in Kenneth MacMillan's Romeo and Juliet? She tells us it's a weirdly out-of-touch experience on that vast stage, almost like being in private. And thank goodness for the cameras.

The lens loved Mick. Those child-bearing lips, to use Joan Rivers’s ripe phrase, always came up a treat in photographs. Did it ever love Keith quite so much? Ever since he started creosoting himself in eyeliner and crumbling like an oxidising mummy before our very eyes, he has been the incarnation of the photogenic rock wreck. Once upon a time, though, when The Rolling Stones were at their creative zenith, the Human Riff presented a young and even ingenuous mug to the camera.

“I was a very good soprano.” Of all the sentences you’d not expect to hear tumbling from the mouth of Keith Richards, that one is up there with "Tap water for me, please, and I do hope this vegan restaurant is non-smoking." He has the addled larynx of a Fag Ash Lil who, when not mopping and dusting, perches on a barstool glugging gin and puffing on Bensons. But once upon a time little Richards did once sing for the Queen. Got a free bus ride up to the London and all, he recalled with a wide-eyed cackle. When his voice broke and he was relieved of his cassock, he was most put out.

This is the antidote to Martin Scorsese’s 2008 documentary Shine a Light, which, for all its technical excellence, depicted the increasingly senior rock band sounding pretty crap. Ladies & Gentlemen: The Rolling Stones was shot at four concerts in Texas on the Stones’s 1972 American tour, hot on the heels of the release of Exile on Main Street.

Aptly, this new documentary about how the Rolling Stones fled from England to the South of France to record Exile on Main Street was premiered at the Cannes Film Festival, with a supernaturally healthy-looking Mick Jagger on hand to give it a promotional shove. Jagger (along with Keith Richards and Charlie Watts) produced the film, working closely alongside director Stephen Kijak to knit together an evocative and emotional portrait of "the greatest rock'n'roll band in the world", at what many would argue was their peak.

The Rolling Stones' Exile on Main Street is such a quintessential rock epic that it ought to be added to the list of things they throw in for free on Desert Island Discs. Defying the old adage that all double albums would be vastly improved by being boiled down into a single one, Exile is such an astounding feast of blues, gospel, boogie, country and flat-out rock that it feels as if it ought to have been a triple album instead.
