Was it Elvis Presley? Lots of rumours about Elvis visiting the UK.
Yes, that's right. here's the Grauniad's take on the story, dated 22nd April 2008:
"Deep in the bowels of Area 51 where they preserve the TRUE FACTS about the REAL STORY behind EVERYTHING, there is a room devoted entirely to Elvis Presley.
Mainly the files relate to the big truths about Elvis, how he's still alive, how he worked for both the CIA and the Mafia and how his plans for a chain of Heartbreak Hotels were scuppered by a lawsuit from Trust House Forte. There is one folder, however, that has particular pertinence this morning, the folder marked Elvis in Britain.
For the past 48 years the received wisdom has been that Elvis only set foot in the UK once, stopping at Prestwick airport on his way home from army service in Germany in 1960. He never left the airport, but told the locals he encountered: "This is quite a country. I must see more of it." He never did.
Or so the story goes, at least. For yesterday on Ken Bruce's Radio 2 programme The Tracks of my Years, a shadowy account emerged of an alternate history, one in which Elvis made another trip to the UK two years previously. A trip to London in fact, where he was escorted round the capital by Tommy Steele, the bloke who sang Little White Bull.
The story was revealed by Bill Kenwright, theatre impresario and chairman of Everton football club, and despite knowing that his mate Tommy doesn't like to talk about it, he didn't half go on at length. "I remember him telling me about when Elvis came to England very quietly", Kenwright I-wanna-tell-you-a-storied. "Evidently Tommy got home one night and the phone rings. A voice says, 'They tell me you're good.' "Tommy says, 'Who's this?' 'Elvis' says the voice. 'Get outta here', says Tommy. 'Are you as good as me?' says Elvis ... and they started this mock rivalry.
"It all came from that. It's quite something isn't it - the thought of them wandering around London together? But the impression I got was that they never got out of the car."
So not quite the missing link between Elvis, Marilyn and the moon landings then, but it's enough to persuade the Daily Mail to turn over their page three to the tale, and send some hack to Woking's New Victoria theatre, where Steele is currently appearing in Doctor Dolittle, to ask the 71-year-old about his secret past.
In a written note to the paper, presumably slipped under a door after five hours of haranguing, Steele revealed his disquiet at the revelation: "It was an event shared by two young men sharing the same love of their music and the same thrill of achieving something unimaginable.
"I swore never to divulge what took place and I regret that it has found some way of 'getting into the light'. I can only hope he can forgive me."
What do you mean, "can"? In the present tense? You don't mean to say ... He couldn't possibly ... Someone call the CIA!"
The door to Sun Records is open for you, sir!
