It's one of popular entertainment's most brilliant inventions: the stealth bimbo. In America, we've got Dolly Parton, whose buxom Muppety-ness camouflages one of our great singer/songwriters. In Spain, they've got Charo, the Love Boat staple and "cuchi-cuchi" queen, whose buxom Muppety-ness camouflages her jaw-dropping mastery of flamenco guitar. Charo's onstage transformation from pidgin-English floozy to flamenco Hendrix has made her an international star for over 500 years, and it's totally worth the 70-mile drive north to Skagit Valley to see her work her magic in person.
