The Doors are opening up again. Former members of the classic rock group are getting back together to tour -- and possibly return to the studio, BBC News reports.

Surviving bandmates Ray Manzarek, 63, and Robby Krieger, 56, have replaced (if that's possible) iconic frontman Jim Morrison, who died in Paris in 1971 of a drug overdose, with former Cult singer Ian Astbury. Ex-Police drummer Stewart Copeland will also join the lineup, as original drummer John Densmore is reportedly suffering from severe tinnitus and unable to play the drums.

The new Doors lineup played its debut gig at a motorcycle convention in Los Angeles in September, BBC reports. But the group is planning a small-venue tour of the U.S. in May and is hoping to land gigs during the summer's schedule of U.S. and European festivals.

The aging rockers also hope to head back into the studio for the first time since 1978's "American Prayer," which featured previously recorded tapes of Morrison reading poetry. Their new material will be "different from the Doors, but decidedly Doors-like," according to keyboardist Manzarek.

Copeland, now 50, has spent his post-Police years composing orchestral and film music, and he'll also reunite with the Police when the group is inducted into the Rock and Roll Hall of Fame next year. Relative youngster Astbury, 40, recorded such hits as "She Sells Sanctuary" and "Fire Woman" with The Cult in the late 1980s and early '90s.
