Dubbed by Rolling Stone magazine as the biggest band of the '70s, Led Zeppelin are due to return to touring, as frontman Robert Plant has finally committed to the project.

Fellow members Jimmy Page, John Paul Jones and Jason Bonham had, after months of uncertainty and speculation, reconciled the possibility of touring without Plant. They rehearsed with a stand-in vocalist and were so impressed with one particular American's talent they were confident they could go on tour minus Plant. Much to their relief, their original frontman finally agreed to join his bandmates, so the new Led Zeppelin tour is now a go.

A source told the Sun newspaper: "The rest of the band had all but given up on Robert joining them, but they were determined to go ahead so had started to seriously explore other avenues.

"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. The band were over the moon when he told them the news.

"They are now forging ahead with the tour plans and they can't wait to get on the road."
