Hounds of the Baskerville + Germans = The Sab?

Here’s a well traveled clip from a 1970 German "Sonny & Cher" type variety show. Want to create pure, undeniably brilliant, entertainment? This is your grocery list.

1. Germans
2. Black Sabbath
3. Sonny & Cher (but German – so, Cindy & Bert?)
4. Sir Arthur Conan Doyle
5. More Germans
6. Use the phrase A-Go Go, liberally.
7…and base it all around crimes stories from 1902.
(if you speak German you will notice the lyrics have been altered)

There you have it. I mean, it seems quite obvious to me, duh.
