That's odd, because all three of those guys are friends. Maybe it was the "getting up at 5am" for the European radio interviews that's to blame for the bad mojo.
According to some newspaper articles and the Randy Meisner Concert Chronology, I believe Randy even played in Messina's band for a couple of years in the early 90s (unless I misundertood something). Messina posted on his Facebook page last year that Randy is someone that he grew close to and cares about deeply.
Rusty goes so far as to call himself a "Randy fan" and doesn't shy away from publicly praising him. In his autobiography, Furay strongly implied that Randy got the initial offer to join Poco due to the influence of Rusty. Rusty didn't like Tim (how could anyone not like Tim?!) but he always loved Randy.
