Bit nerdy but the revolving old/new mash-up was the Union tour is what you saw, 'An evening of Yes Music Plus' was the marketing tag for the ABWH tour a year or two earlier.
Never the less, with the live albums piling up, the new members replacing older members who replaced original members, and the tempos all slowing to a snails pace, and the key voices separate and faltering, it's got to be time to call it a day with some dignity. Well done Dr B.
