Don't think so. He just simply said he'll be there wearing the t-shirt. Besides I don't think he would wanna keep track of who's coming or not and even if no one turns up (unlikely) he might just be happy to walk by himself to take photos
At the gathering point. We waited for about 10 more minutes before moving off.
We went one round chinatown exploring the alleys and various places like Sri Mariamman Temple. For those who do not know, SMT now got charge if you want to take photo or video within their grounds. We were practically a contingent of photographers moving around chinatown like a tidalwave.
Didnt really take much pictures since was there mostly to ask him about some things and to observe how he takes his photos so sorry for the lack of photos of the outing.
