The first time the Rolling Stones played Eel Pie Island, legend has it there were just 12 people in the audience, one of whom had overindulged in Newcastle Brown Ale and fallen sound asleep.
By the time they had finished their weekly residency five months later, they had a record deal, a full-time manager, a small army of fans and a reputation as Britain's hottest band.
When Rod Stewart first went to the island, he was a penniless 19-year-old who worked at London's Highgate Cemetery by day and busked at Tube stations by night. Within a fortnight he was a full-time singer, touring the UK, with a wardrobe of three-piece suits and a growing collection of besotted female groupies.

Meanwhile, 16-year-old Eric Clapton was so poor, he would swim across the Thames to avoid paying the twopenny fee to cross the bridge from Twickenham to Eel Pie lsland.
'We'd put our clothes on top of our heads, swim across the river and get to the other side with our trousers all wet,' recalls his wingman Dave Brock. Brock went on to find fame as the frontman of psychedelic rock act Hawkwind, while Clapton secured a job playing guitar for the Yardbirds, then John Mayall & the Bluesbreakers.
The venue where these — and many other — future pop legends gained their big break was on the ground floor of an imposing but rather tumbledown three-storey building called the Eel Pie Island Hotel.
Built as a riverside resort for wealthy Victorians on the little nine-acre island in the middle of the Thames, by the mid-1950s it had fallen into disrepair. Then, over the course of an extraordinary 15 years, its tatty ballroom became one of the best live music venues in Europe.
The widely forgotten story of how it shaped the careers of everyone from the Kinks to Elton John, David Bowie and Pink Floyd is the subject of a new BBC Four documentary film called Rock'n'Roll Island, now available on iPlayer.
It tells how the hotel became a talent factory and influenced a whole generation. Like the Cavern Club in Liverpool or the Hacienda in Manchester a few decades later, it was at the centre of a cultural revolution. And like many chapters in rock'n' roll history, its story is one of sex, drugs and excess.
The jazz musician George Melly once said that in its heyday 'you could see sex rising from Eel Pie Island like steam from a kettle'. Martin Turner, of the rock band Wishbone Ash, recalls that 'the minute you walked in the door, the waft of marijuana immediately hit you...you could not be smoking anything and just get stoned being in the room'.
Little wonder that the venue was regarded as every parent's worst nightmare. One outraged local newspaper, whose reporter visited the island undercover, dubbed it 'a beatnik-infested vice den'.

In 1956, a prosperous antique dealer with bohemian tastes, Arthur Chisnall, bought the hotel and hired jazz acts (many from the U.S.) to entertain young punters in the ballroom that had been used for tea dances in the 1920s.
A prominent philanthropist, Chisnall thought the venue might attract local teenagers who were in danger of going off the rails. He would offer them support and advice on education before letting them listen to visiting bands.
Young people had other ideas. When a bridge was built linking t h e i s l a n d t o Twickenham in 1957, it was easy to visit. And with precious few other venues where young people could dance, drink and kiss without attracting opprobrium, it was soon a huge success.
In June 1961, on the club's fifth birthday, Chisnall was interviewed by the News of the World and made the following startling claim: 'This place started as a jazz club. 'Now it is
