Robert Smith Interview 1986 in a Munich Beergarden by Babette Einstmann 

Interview June 15th, 1986
Munich, Germany, somewhere in a beer garden.
(In the video it shows '85, but that must be wrong, since he talks about their gig the day before at Nürburgring playing on the same bill with Simple Minds, which was the Rock am Ring-Festival on June 14th 1986.)
It was broadcast in a Cure-Special on german tv in 1992 (they played Fascination Street before fading into this old interview, if you're wondering why you hear a song from 89 in the background).
See here for the full broadcast: • The Cure - German TV S...
The interviewer is Babette Einstman, who some years later became famous on german TV as a TV presenter.
If I find out how to add subtitles, I might add them later or post it here, as I think her stupid translations and comments are quite essential to the fun and dumbness of the whole interview ;-)
