This article from Rolling Stone regarding the gray-area live recordings of the Beatles recorded in Hamburg's Star Club during the Beatles' 1962 performances there refers to the venue as a "strip club."
Other media outlets have done the same. I see more than a dozen references to it on Google News.
Most likely, all these references stem from the same initial report or press release. But they demonstrate a lack of homework and general knowledge. Rolling Stone, in particular, ought to know better.
The Star Club was a showcase for rock'n'roll in the early 1960s on the admittedly sleazy Reeperbahn. But it wasn't a strip joint.
The only strip club the Beatles ever performed at was, briefly, Liverpool's New Cabaret Artists Club, where they backed up one of the dancers during her performance.
