I know that even though the events after Tango were ugly, he must have had a decent relationship with the band when they were touring Behind the Mask as he appeared onstage during Landslide at one (or more) show(s).

so he must've had a good enough working relationship to be on that title track and when Time was being recorded was just after the inauguration for Clinton with Don't Stop. The band kind of reminds me of the Beach Boys later on their careers in that, they could regroup after years for weird one-offs and then just simply say "see ya", "see ya" and hope on their respective planes and not see or talk to each other for years more.
