There are quite a few moments in the 1970 Royal Albert Hall show and one or two in the Danmarks Radio performance. I’m sure there are more and many that didn’t get filmed. And even then, not smiling at each other during shows isn’t indicative of them not being buddies. There are also quite a few pics n stories of Jimmy and Jonesy being friendly with each other Personally I get the impression they were all friends with certain dynamics being closer than others (robert and Bonzo, robert and jimmy, bonzo and jonesy) edit: also jimmy has spoken fondly of jonesy on multiple occasions
