It strikes me how people out here are solely looking at Bruce when talking about "shots" or being open. Just his shots? Let's not forget that Steve openly complained about Bruce when interviewed, during Bruce's farewell tour (1993). Bruce explained his side very well in that interview Talisman posted.
Did Bruce say anything that's not correct? Even if he did, it looks like he fired back, and I'm not sure if he would have said anything if he weren't the target first. As I've said, sometimes it's good to be open, defending yourself is one of the best reasons.
By the way, after all these years, I yet have to hear footage that backs Steve up when he says he couldn't hear Bruce.
