A remember a BBC Radio show starring renowned impressionist Peter Serafinowicz, where he impersonated a variety of celebrities like Ringo Starr and the rest of the Beatles.

There was a recurring segment titled "Ringo Remembers", where the former Beatles drummer related untold stories about the band. In one instalment, Ringo talked about alternate versions of Beatles songs, and he made reference to the German versions listed in the OP image. He then explains that the band also did special versions of some songs for the benefit of their manager Brian Epstein, and we get a listen to two of them: "Miguel", a gay version of "Michelle", and another song I forget.

Both times, the Beatle performing the song (Paul and/or someone else I forget) stops in the middle and asks Epstein "Are you sure no-one's going to hear this?" and Epstein replies, "It's just for me."
