Frank Zappa...a true & gifted showman...and very interesting person. Per wiki:
“He always encouraged his fans to register to vote on album covers, and throughout 1988, he had registration booths at his concerts.[9]: 348 He even considered running for president of the United States as an independent.[9]: 365 [137]”
He was a libertarian and probably a curmudgeon. In the High Times interview back, hmm, early-1980s or maybe 1890s I dunno, he talked about being on a plane next to a Spanish politician (maybe their head of state) and being asked for some advice. His political aspirations were probably never 100 percent serious, but he said his platform was to dismantle the federal gov't except for the DoD. Sort of constructionist. :^)
