And do you know what Brian Epstein did on this day 50 years ago? Yes, he was at the press conference, but he also was on the Tonight Show with Johnny Carson! I found this out when I was doing research for my book. Brian was interviewed all by himself and as far as we know, no audio, video or even photographs exist. We wouldn't have even know that this happened if it wasn't for a major Brian Epstein fan that wrote about it in her diary!
Since the Beatles wore the same thing during both press conferences, it is impossible to tell from which part of the press conference the photos are from.
