I guess if you look at this from every aspect, it is impossible to say what would have happened but I think the point of this thread is that in our opinion, given what we know and see Richie contributing from interviews, live shows and the amazing energy he brings to songs with his guitarwork and vocals, would the success be there without that?

It wasn't asking about Tico's marriage or Desmond Child's input - we have to try and answer this as the title of the topic asks.

Bon Jovi without Richie?

Given Child's input and Tico's divorce and everything else Becky mentioned as 'matter-of-fact', would they have survived without him?

I don't think so.
