Possibly. I think Gene is the more gregarious. Paul did sign autographs though after the first Kiss gig in Manchester when he exited the Free Trade Hall sans make-up (in the days when no one published pics of them without the slap). Peter Criss snuck past and onto the coach before anyone realised. Gene was unmissable and pretty much announced himself but security wouldn't let anyone near him.
On their 1980 tour my friends and I had backstage passes for all four of their gigs and we did get the chance to chat with Gene, briefly, but he was quite visible; didn't see much of the others. My main memory, which I've recounted before I'm sure, is him holding court and slating Girl, the support band, because they pulled out of the final show at Wembley due to lead singer Phil Lewis having a cold. Gene was not impressed, being very much of the show must go attitude.
People love to slate Kiss but one thing about Simmons and Stanley is they are bright guys and extremely professional.
Anyway, Simmons was obviously very fond of Eddie but he and Dave is another story.
