Fancy etymology of «Planète Zen».

As the exact origin of the band's name remains a mystery, we can feel free to imagine whatever one wants...
Maybe it's just related to Mars and those shining, sparkling jewels scattered in the infinite darkness of the Universe. And «Planète Zen» sounds quite cool, after all, why bother and try to find cryptic hypothesis?
Imagine now you are a comics fan. I mean old good super-hero comics like Marvel and so.
Then you certainly heard about Strange, this mythic comic whose number 1 is greedily seeked for by many marvel-maniacs... Guess who was starred on the cover? The Silver Surfer. And what was this super-hero's business? To feed Galactus, the planet-eater, in order him not to destroy the Silver Surfer's world, planet Zen-La. Wait a minut... Did I say «Planète Zen»???

The rumor is on its way...
(Last question: Is Charlie the Spacedriver the Silver Surfer?)

Shut up!
