Jimmy Page: Led Zeppelin Reunion Tour Never Happened Because Robert Plant 'Was Busy' Some of us thought that we would be continuing,' says guitarist ....

It turns out that Led Zeppelin fans weren't alone in thinking the group's 2007 triumphant reunion concert at London's O2 Arena would lead to a tour. "Some of us thought we would be continuing, that there were going to be more concerts in the not-too-distant-future," Jimmy Page tells Rolling Stone Senior Writer David Fricke in the new issue, on stands Friday. "Because there was a lot of work being put into the show."

Ultimately, Robert Plant had no interest in carrying on. "He was busy," says Page. "He was doing his Alison Krauss project. I wasn't fully aware it was going to be launched at the same time. So what do you do in a situation like that? I'd been working with the other two guys for the percentage of the rehearsals at the O2. We were connecting well. The weakness was that none of us sang."

With Plant out of the picture, Jimmy Page, John Paul Jones and drummer Jason Bonham continued rehearsing together in early 2008. "We didn't do any professional recording," says Page. "We just had a little digital recorder. I thought it was good. I wasn't going to away from it. But the weakness came up again. It was, 'We gotta have a singer.'"

Steven Tyler Makes First Ever Visit to the Playboy Mansion ...

Steven Tyler walked up the driveway to the entrance of the Playboy Mansion in Los Angeles like it was a second home. Surrounded by a large entourage as he was led to the red carpet, Tyler stopped to bare a Cheshire Cat's grin as he looked at the four lovely Playboy Bunnies waiting to pose for pictures with him. The rock star and the equally iconic home that has hosted thousands of parties seemed made for each other, but this was Tyler's first visit ever to the Holmby Hills grounds.

How was that possible that in all the years of Aerosmith's success, the frontman had never been to one of the famous Halloween parties or a Midsummer Night's Dream? "I was too busy in someone’s bathroom getting high," Tyler said. "I was too busy on tour, I was too busy writing songs. We were just busy."
