I am a fanatical Floyd fan.
As a music journalist, I disucss band dynamics with musicians all the time.
Over years, people change, and previous non-assertive people can take on a more 'leadership' role in a band, which sometimes works, sometimes not.
I believe that all the band were complicit in the split with Waters - Waters for his 'takeover' attitude, Gilmour for not necessarily understanding his viewpoint, and Wright and Mason for fence-sitting.
But the truth is, we don't know, we are not them and we were not there.
We get edited interviews, and media soundbites, which don't address the situation in any depth, or lead to any understanding - for them as much as us.
