Two remaining members of The Doors have been banned from using the group's name while touring with a revamped version of the legendary 60s act.

The LA court order also requires Ray Manzarek and Robby Krieger to share profits from their group with the original Doors partnership.
Doors drummer John Densmore, singer Jim Morrison's parents and those of his late partner brought the legal action.
The Doors are known for hits such as Light My Fire. Morrison died in 1971.
After the ruling Densmore said in a statement: "I'm just so happy that the legacy of the true Doors, and Jim Morrison in particular, has been preserved by this decision."
Under an agreement struck in 1971, following Morrison's death in Paris, all three surviving members, as well as Morrison's estate, must agree on any use of the Doors name and logo.
Keyboardist Manzarek and guitarist Krieger have been touring as The Doors of the 21st Century with former The Cult singer Ian Astbury since 2002.
In March 2003, former Police drummer Stewart Copeland sued Manzarek and Krieger after he was dropped from the reformed band.
Earlier in February 2003, Densmore began legal action against them for embarking on a tour without him. He was joined by Morrison's parents George and Clara and the parents of Morrison's late girlfriend Pamela Courson in April that year.
Densmore said he wanted the band billed not as a Doors gig but a concert by "the former members of the Doors".
He had been invited to join the band but he said his ears were too badly damaged to continue playing drums.
The Doors rose to fame in the late 1960s. After Morrison's death the band eventually folded.
A biography of the band No One Here Gets Out Alive was published in 1980. Director Oliver Stone's made the movie The Doors in 1991. The band was also inducted into the Rock and Roll Hall of Fame in 1993.
