Sir Elton John has joined fictional rock band Spinal Tap for a new version of their classic song Stonehenge

The original Stonehenge appeared on Spinal Tap's debut album This Is Spinal Tap, released in 1984 alongside the cult mockumentary film directed by Rob Reiner.

Starring Michael McKean, Christopher Guest and Harry Shearer as the fictional heavy metal band members David St. Hubbins (played by McKean, 77), Nigel Tufnel (Guest, 77) and Derek Smalls (Shearer, 81), it famously included a gag where the band orders a massive Stonehenge replica that arrives at an absurdly small size.

Spinal Tap II: The End Continues sees the band reunite for a final concert, with Martin 'Marty' Di Bergi (Reiner, 78) once again directing the documentary.

The album going with the movie is set for release on 12 September alongside the film's theatrical debut, and features other collaborations with Sir Paul McCartney, Garth Brooks and Trisha Yearwood.

In an interview with Empire magazine, the band members reflected on their decades-long fictional partnership.

Nigel Tufnel said: "We've had arguments over the years and then made up... arguments, make up, arguments, make up. But there's no secret, because there's no solution for an old friendship."

David St. Hubbins added: "I think that the more we can leave our egos at the door, the better. But it's not easy. I carry my ego everywhere, but having a big ego is like having a big dog. You can't expect other people to feed it for you."

The new project continues the satirical exploration of rock culture that has made Spinal Tap a lasting icon of comedy and music parody.

This Is Spinal Tap, released in 1984, was hailed as a groundbreaking mockumentary that satirised the excesses of rock bands.

Created by Christopher Guest, Michael McKean and Harry Shearer, it pioneered the comedy-music genre and influenced countless filmmakers and comedians, becoming a cult classic and a lasting cultural touchstone in music and comedy.
