I'm reading What a Long Strange Trip right now. The one thing I'm coming away with, that I never would have suspected ahead of time, is that Weir may well have been the least liked guy in the group. McNally, time and again, just by the way he phrases stuff, puts Weir down. Things like Weir getting into a scuffle with Bill, and all that a crew member does to intervene is place his shoe between Bob's head and the pavement, almost like he wants to see Bob get his ass kicked, but not get seriously injured. Mention of Weir's always being late to airline flights, but phrasing it with a lot of suspense to drive home the point of Bob's being such a predictable misfit. Hunter's eventual refusal to write songs for Bob and literally telling Barlow, "He's all yours!" (or something to this effect) His being kicked out of the band. Haven't gotten to it yet, but it will come up, the deliberate turning down of Weir's vocals by the soundboard guy.
Then, from a JDarks YouTube, Darks makes mention of the fact that Jerry and Bob never really hung out together like you would think they would, their being the front men, the main vocalists and guitarists. That they weren't "buds."
And now this on stage blow up of singing too many verses, and Weir getting sworn at.
I'm getting the feeling that Bob irked everyone. Even to this day, wasn't there, until this last tour, a serious falling out between Weir and Lesh that lasted years?
