Let's face it: Some rock and roll reunions look good on paper but the actuality of a legendary group sounding great so many years later is the big question. Thankfully, in the case of Led Zeppelin, their 2007 reunion is secure.

When Robert Plant, Jimmy Page, John Paul Jones, and Jason Bonham — son of the late John Bonham — came together for a one-off show at London's The 02, the resulting magic shook the heavens. The proof, as they say, is in the pudding.

Celebration Day, the live document of the show released in 2012, found Page, Plant & Co. in top form — running through Zeppelin classics such as "Dazed And Confused," "Black Dog," "Stairway To Heaven," and "Whole Lotta Love" with an urgent fervor. The live set would earn the group a GRAMMY for Best Rock Album at the 56th GRAMMY Awards.

As if a GRAMMY wasn't enough, the group's legendary frontman looks back fondly on the gig in a new Rolling Stone interview.

"It was magnificent. We hit a home run that night, which is something that we were really fearful of," said Plant of the reunion show. "There was probably more riding on that than we would care to believe. Our performance was crucial, but we could reproduce sound in a much more reliable way, so we could be kicka**, and sound kicka**."

Plant, however, prefers to look forward as it relates to his career. In October he will release a new studio album, Carry Fire, which has been preceded by the single "May Queen." And though contemporaries such as Eric Clapton, Keith Richards and Bruce Springsteen have written their life stories, don't expect a memoir from Plant anytime soon.

"What I know between my ears here is priceless. It's magnificent, sometimes tearful, but mostly cheerful," he said. "There have been highs and lows and a lot of adventure, and I keep it hid."
