Led Zeppelin frontman Robert Plant has revealed that he found the responsibility of organising band's reunion show last year hard to deal with.

"The endless paperwork was like nothing I've experienced before,” he told GQ Magazine.

The band's concert at the O2 Arena in London was one of the most anticipated in living memory, attracting over 1 million applicants for just 18,000 tickets.

“I've kept every one of the emails that were exchanged before the concert and I'm thinking of compiling them for a book, which I feel sure would be hailed as a sort of literary version of Spinal Tap (semi-fictional heavy metal band featured in spoof documentary This Is Spinal Tap.”

Despite relentless calls for the group to announce more shows, nothing has yet been confirmed.

"Led Zeppelin's never been about the fans. We've always been about four guys coming together to make thrilling, disturbing rock 'n' roll. On our own terms,” Plant added.
