The Restaurant at the End of the Universe by Douglas Adams

"The Hitchhiker's Guide to the Galaxy notes that Disaster Area, a plutonium rock band from the Gagrakacka Mind Zones, are generally held to be not only the loudest rock band in the Galaxy, but in fact the loudest noise of any kind at all. Regular concert goers judge that the best sound balance is usually to be heard from within large concrete bunkers some thirty-seven miles from the stage, while the musicians themselves play their instruments by remote control from within a heavily insulated spaceship which stays in orbit around the planet--or more frequently around a completely different planet.
Their songs are on the whole very simple and mostly follow the familiar theme of boy-being meets girl-being beneath a silvery moon, which then explodes for no adequately explored reason.
Many worlds have now banned their act altogether, sometimes for artistic reasons, but most commonly because the band's public address system contravenes local strategic arms limitations treaties" (221, Ultimate Hitchhiker's Guide).

"...it is a well-known fact that those people who most want to rule people are, ipso facto, those least suited to do it . . . anyone who is capable of getting themselves made President should on no account be allowed to do the job" (278).
