Paul Sontagg took part & said "It was way out of left field, and we had an absolute ball. We met in Trafalgar Square at 3pm, were split into groups of around 25 then headed down to the Charing Cross Station. After lining up for the front carriage, we boarded then had to act like we were travelling alone and didn't know anyone else on the train. After stripping our jeans/trousers off and into our backpacks, putting our shoes (or cowboy boots in my case) back on, then act like life was normal. The looks from the innocent bystanders was priceless, it was a very unique way to spend a Sunday afternoon." There's more on his blog
Rammi the organiser was updating from Twitter, and was delighted with the amount of people who turned up this year.
The video from you and i films of commuters reactions below has that usual mix of Londoners to unusual Tube encounters - from complete indifference, sly looks to laughter and someone actually deciding to join in.
Well done to those who braved it and it looks like No Trousers on the Tube is going to be a permanent fixture of the Global No Pants Subway Ride.
