Elton John's "upmarket Spinal Tap"!

Sir Elton's long-term manager Bob Halley came up with the concept three years ago, convincing the singer of its potential based on the lives of other male rock stars including Rod Stewart, Mick Jagger and Freddie Mercury.

Also involved in the project is songwriter Bruce Roberts, Michael Edelstein and screenwriter Cindy Chupack, who worked on Sex and the City.

"Elton's been very public about the craziness of his life," Mr Edelstein said.

"There's nothing like the world of rock'n'roll. He's got a hairdresser, valet and two straight SWAT bodyguards on staff. They've assembled their own wacky family.

"Elton's witty, relevant and has always been on the cutting edge in both his personal life and musically," he added.
