Boney M were a German band engineered by the same dude, Frank Farian, who concocted Milli Vanilli.
Unlike Milli Vanilli, with Boney M, there was something there. Great Fashion sense. Excellent moves. Insane Abba-like ESL choruses and crazy sweet disco hooks. You still can hear them getting played regularly in bars, discos, cafes and wherever else just about anywhere east of Budapest, where they're easily on equal status with the Beatles.
