Below are the applicable parts of the article involving Jon and Rick. I find that Jon's comments are entirely in keeping with others from various interviews over the past year and as such were causing fans to speculate that the end was near.
Jon
This year did find Howe, White and company as the only Yes on the road. Former members Jon Anderson, Rick Wakeman and Trevor Rabin had started touring as ARW in 2016 and then adopted the Yes moniker as well shortly after the group's 2017 Rock and Roll Hall of Fame induction. This year, however, the project was dormant and the three worked on other projects. "It's a long story," Anderson -- who released a solo album, 1000 Hands: Chapter One, this year, and is writing a memoir -- says. "Life happens when you least expect it. You expect something to go for a long journey, and then all of a sudden it's not...because of life. People have a life they want to live and go through. It's not a good explanation, but it just doesn't work at times. There's maybe 20 versions of Yes I've been in, and every one's been fantastic -- but it was always chaos in there for some reason."
Rick
Wakeman, who says he opposed ARW going out as Yes, adds that the trio is planning one last tour for 2020 and may possibly record some of the new music they've been writing during their time together."We feel it's sort of come to the end of the road," says Wakeman, who will be mounting his first North American solo tour in 13 years starting Sept. 21 in Annapolis, Md., and is also recording a Christmas Portraits album of solo piano holiday songs for the fall. "None of us are spring chickens anymore, although Trevor still has a 6 in front of his age, whereas Jon and I don't. I think we'll thoroughly enjoy another (tour) and then I think we can sort of proudly close the lid on it, very happy in our belief that we've done it proud."
As for any new material, Wakeman says that the trio "has got a couple of things we've worked on that we think are good enough, but we always said that unless it was really of a high standard we felt really proud of we wouldn't just release stuff for the sake of releasing it. I think when we start on the farewell dates we'll analyze what we've done and go, 'OK, what can we make of this?' I would like to think we can leave one final burst of music that we can be proud of and, perhaps, we'd like to think that Yes fans have been waiting for."
