Oh dear. Nick. If you want to make a fresh start with a new band, you really shouldn't begin by criticising your previous band. It goes without saying that it severs ties, but it also associates negativity with a new product, ie. Tarmac Adam. If the press ask you about your time in CH, then yes, respond. You are more than entitled to have your say. But respond appropriately. It's no secret that you and Neil had problems - hell, everyone had problems with Neil at one point or another. But discussing them sourly now will only cast a bad light on your new band. And to be honest, if you're with a band that is starting from the ground up, you can't afford to piss anybody off. So if Neil said something unflattering about you when CH broke up, you don't come out seven years later and retaliate. It gives the impression to the press and the public that you really can't let go of grudges, and i'm sure that's not the case.
In saying that, i'd also be careful about who you discuss things with in the media. As evidence shows, they have a sneaky way of getting quotes from people that may have been said off-handedly, and milking it for all that it is worth.
*steps down from the soapbox* I didn't say that as eloquently as I would like, but I haven't had my coffee yet.
