Rockers Led Zeppelin are to be reunited with ex-band mate Robert Plant for their upcoming tour, according to reports.
The English rock band had originally resigned themselves to touring without Plant and had been forced to rehearse with stand-in singers.
However Plant agreed to join guitarist Jimmy Page, 64, bassist John Paul Jones, 62, and drummer Jason Bonham, 42, after it was revealed that they had found an American singer good enough to take his place.
The tour, planned for next summer, follows the huge success of their one-off reunion show at the O2 Arena in London last December.
Recently Plant has been busy working on his collaborative album with country singer Alison Krauss.
Their album "Raising Sand" has been a huge success and was nominated for this year's Nationwide Mercury Prize.
However a source said: "When Robert realised the band were serious about doing it without him, it made him think long and hard.
"He realised he couldn't face the thought of not being involved.
"They are now forging ahead with the tour plans and can't wait to get on the road."
Led Zeppelin formed in 1968 and, in their time, sold more than 300 million albums worldwide, including 111.5 million in the United States.
They are regarded as one of the first heavy metal bands and in 2006 Rolling Stone magazine labelled them the biggest band of the 1970s.
They split in 1980 when drummer John Bonham, Jason's father, died at the age of only 32.
