Jon, David and Tico seem to be all over the place in the UK at the moment promoting the documentary. There was a premier of the documentary in London last night (I presume just the first episode?) and they attended. It's bizarre that Richie isn't even invited to these things, but is being used in the promo big time. Having said that Phil, Hugh, Everett and Shanks didn't seem to be there either. There's definitely a reason for Richie's silence/absence, but I don't think it's regarding any big reveal in the 4th episode...
