Catchy German cover of Black Sabbath's "Paranoid" but with lyrics about Sherlock Holmes

Famed German schlager-psych duo Cindy und Bert belt out a cover of Black Sabbath's Paranoid but with alternate lyrics about, um, Arthur Conan Doyle's Sherlock Holmes novel 'The Hound of the Baskervilles.' It's the B-side from a very rare 1971 7' featuring their cover of Neil Diamond's 'Holly Holy.'
