At more than two and a half hours, this was a long show. Whether it could be considered a wholly successful one or not might depend on a tolerance for relaxed tempos and extended guitar solos - at least in an occasionally sluggish first half, as the UK leg of the folk rock supergroup's European tour wound its way to Glasgow.
Stephen Stills's weary-sounding husk of a voice aside, the trio (plus four-piece backing band) started solidly enough with Carry On/Questions, before rolling into a surprisingly laid back Marrakesh Express, which set the tone for much of the early part of the night.
By tenth song Deja Vu, and a series of flashy instrumental breaks featuring every member of the band in turn, David Crosby and Graham Nash cried "We have all been here before," in exquisitely anguished unison, and it was certainly starting to feel like it.
Rescuing things was a gritty Love The One You're With, which set up a much-improved second half featuring greater variety, more focused playing, and frankly, most of the night's best material.
Of the handful of new songs, Nash's Burning For The Buddha sounded as earnest as you'd expect a tune about the self-immolation of Tibetan monks to be, but wasn't half bad.
Other highlights included a Steely Dan-ish make-over of Crosby's Byrds reject Triad, and a driving Cathedral, which did eventually kick on to something approaching urgency after floating in, under slightly bizarre circumstances, on a cloud of dry ice, red spotlights and synth-pad atmospherics.
The reaction after easing into the home straight with a winning Nash two-fer of Our House and Teach Your Children seemed to spur them on. An electrifying Almost Cut My Hair was followed by a frenzied Wooden Ships, Stills's six-string mastery finally channelled into peaks of near torrential intensity. An encore of Suite: Judy Blue Eyes closed the evening in anthemic fashion.
No disgrace then that three men with an combined age of 211 need a bit more time than some to get warmed up, but can still remember how it's done when suitably roused.
