Robert Plant on Why Jack Black’s ‘School of Rock’ Was Allowed to Use ‘Immigrant Song’

Led Zeppelin vocalist Robert Plant is opening up about why he allowed Jack Black's School of Rock to use "Immigrant Song" in the movie.

Speaking with Vulture, Plant said, "My response is: Why not? Our songs didn’t come from Valhalla. It’s not a preferred destination, either," he says. "I like the idea of taking the hammer to another time."

"Jack Black made a magnificent meal of it," Plant adds. "It’s a killer guitar riff. What a shame 'Immigrant Song' isn’t easy for kids to play, by the way. Everyone gets it, young and old. It’s a great song. Not only slightly ridiculous but ridiculous. Considering that we wrote it in midair leaving Iceland — a fantastically inspiring gig and an adventure, beyond which there will be no books written. To give it to the kids is important. Send it up, send it down, and just keep sending it."

So, how did Black do? Plant was very impressed, saying, "Jack Black got it right down..." He adds, "All of my grandkids have all been able to play Jack Black’s riffs. I think it was exactly the right thing to do, with School of Rock, to blow our myth up into the sky for a while. Because it’s all myth. It doesn’t matter. I’ve watched the film and find it funny."

When it comes to which movies are allowed to use Zeppelin songs, Plant says there is a process that movies have to go through to get approval.

"I’m not responsible for all the decision-making when it comes to where we allow our music," he says. "It’s group decisions... We have to go through the whole thing together. Not to generalize, but quite often we’re presented with a scene that’s in the script or cuts of a film. When there’s something uncomfortable, unpleasant, or overtly just not the right place for our music to be, we say no. The music is dynamic. There it is, sitting there, and happily waiting for romance or nuance or drive that should link to a film with substance."

Led Zeppelin and their catalog as a whole have become more beloved and revered with time as they've been passed down through generations and become standards for which future bands are measured.

So, how do you honor one of the greatest, most influential bands of all time? Hunker down with a fifth of Jack Daniel's, a 2-liter of Coke and dive headfirst into the "Zep-a-Thon." Dubbed so by Jack Black when the band received the Kennedy Center Honors in 2012, the "Zep-a-Thon" is a musical binge session where you listen to all of Zeppelin's eight studio albums (plus the 1982 compilation album Coda) in one sitting.

"Led Zeppelin: The greatest rock and roll band of all time," said Black. "Better than The Beatles, better than the Stones, even better than Tenacious D."

Black continued, "If you don't agree with me, it's because you never did the 'Zeppelin Marathon.' The 'Zep-a-Thon' is when you sit your ass down and listen to all nine Zep albums in a row ... [It's] the thing every true fan must do at least once in their lifetime. The pilgrimage to heavy metal Mecca."

For the author, this binge wasn't all for pleasure, even though it was oddly fulfilling. The purpose of doing this was for research in order to rank all 92 original Zeppelin tracks.

Exhausting? Yes. A bit much? Maybe, but crazier things have likely been committed in the name of Zeppelin throughout the past five decades. We're positive a simple Google search will yield many things that prove this statement correct. However, we're almost too afraid even to find out what those things are.
