Are we putting in doubt what Ed Bicknell and most of the people involved told about the oes tour, just because we are fans and they smiled and interacted on a stage for two hours every show?
I don't think there's any reason to doubt it. I mean, why should Ed, John, Mark or anyone, 30 years later, tell the world a lot of nonsense about the tour? And, by and large, they're all saying the same thing, namely that it was all too much for everyone involved.
After all, there must have been a reason why Mark took six years to get the band back together, and why he decided to put an end to it after that tour.
I'm sure that there were also good bits, and they enjoyed being on stage and interacting with audiences, because that's what being a musician is about. And of course, they were/are all highly professional about it, which means you just keep going and do the job you're being paid for.
