Mystery of the Day
Minutes after seeing the top photo for the first time, I stumbled upon the picture of Robert and noticed that it had to be taken on the same night. The stage was unmistakable, with a huge Led Zeppelin sign in the background and an eerily elongated platform where the band stood miles apart. Robert was indeed wearing the bolero jacket, which is my favorite. The photos were taken in Hiroshima September 27 during their 1971 Tour of Japan.
Thanks to a little teamwork from @aodetoharrison for posting the initial photo and also to @zephantom519 for providing the location and date.
