Those three were taken in the summer of 1996 as passport photos in some picture booth inside London's subway. The fourth went on my Subway Pass.
This trip to London was great fun. I stayed there three weeks at a B&B in Wanstead in the East End. The landlady just did not care what I was wearing, so I was shirtless and barefoot all the time in the house.
Outside was fun too. We had great weather all the time, so I just did not even bother taking a shirt with me. All three weeks were spent shirt-free. No place I went was a problem. Shopping at Virgin Megastore or going see a movie on Leicester Square shirtless was just great.
Most exciting moments were in the subway and busses. I always rode them shirt-free, and was also barefoot two or three days each week. And never had any negative comment. Try London for your next holidays ;-)
