Katy Perry is releasing a YouTube Red documentary about her YouTube live stream

Katy Perry is releasing a full-length special on YouTube Red about the time she live-

streamed her life on YouTube for four days this summer. The documentary, Will You Be My Witness?, will premiere on YouTube’s subscription service on October 4th, Billboard reports. Will You Be My Witness? is apparently going to give viewers a behind-the-scenes look at the June live stream event, during which Perry talked to fans, performed songs from her most recent album, Witness, and talked to celebrity friends like RuPaul and Mario Lopez. It’s not clear how a documentary about those four days is going to add much more to the story, seeing as the live stream itself was already supposed to be — as Katy puts it in the trailer — “uncharted territory.”                                                                                                                                                                        https://www.theverge.com/2017/9/28/16379520/katy-perry-documentary-live-stream-youtube-red
