Just found these pics on Blue Lug Blog:
It seems that Mr. Paul Smith (yes, the man behind that often very stripy mens' fashion brand) is almost riding a track bike, and a Keirin bike no less, in Tokyo. Interesting indeed.
Well, he did have that bike design collaboration project with Mercian Cycles last year, more about his cycling pedigree here too. The pictures show that he did visit Blue Lug shop but I'm guessing the picture just has him trying out someone else's bike outside of the shop.
