Waters was horrible towards Gilmour, Rick Wright (RIP) and Nick Mason. He zeroed in on Wright cause he was a pretty gentle soul. Even Gilmour said that Waters destroyed Mason and Wright’s confidence. Gilmour actually stood up to Waters.
Indeed he did. And when Gilmore brought the band back together for a few more albums and concert tours, he did so without Waters. From the things I heard in interviews and such, Gilmore had had enough of Waters and wanted him nowhere around Wright and Mason (who quit the band until Waters left).
Waters sued the band for using the name Pink Floyd but he lost in court and Gilmore, Wright and Mason got to use Pink Floyd. That had to piss Waters off big time.
I saw the post Waters Floyd in concert twice and both times it was great. I didn’t have to put up with his political rants either. Just sweet sweet music.
Don’t know if Floyd will continue since they lost Wright, but if they do so without Waters they will still find a fan in me.
