Offstage, all five seem surprised, amused and even a little embarrassed about working together again.
"The music is easy," states Nicks earnestly. "It's the other stuff that's hard. But I realised a long time ago that there is no Fleetwood Mac without Lindsey. If it can't be with him, then let's not do it."
The "we all love each other" party line may be trotted out once too often, but Nicks's platitudes are not completely misguided. Buckingham remains the band's musical linchpin; instilling a touch of barely-controlled mania into the jerky, angular 1979 hit single Tusk ("Back then I really wanted to be in The Clash," he will confess later) and playing the tetchy, demanding musical foul to the more melodic Nicks and Christine McVie. It's little wonder the band foundered without him.
Go Your Own Way sees out the main set, Buckingham and Nicks once American rock's most beautiful couple, all too quickly a grudge match in cheesecloth and flares ham it up, trading knowing looks and even returning to the stage holding hands.
"Sure, we're playing it out," admits Buckingham, looking faintly appalled. 'But when I quit the band, Stevie and I still had unresolved issues. It's kinda nice to be getting along again.'
Cosseted by a 150-strong staff, including no less than seven fractious managers, the saga of this oddball gathering of ex-wives and husbands continues to play in the manner of what Christine McVie freely describes as ‘a mini-soap opera’.
"America wants a happy ending to the fairy story," she laughs. 'I'm sure there were people out there tonight who genuinely believe that Stevie and Lindsey will be reunited, and everything will be alright again. Let me say now that will never happen."
"Y'know before Lindsey and I joined we had to steal ourselves not to go into stores," recalls Nicks, stepping into the stretchiest of limousines. "Six months later we were earning $400 a week each and I was totally famous. We used to pin $100 bills up on the walls of our apartment just for fun. You go through that with someone, you don’t forget."
At the airstrip she follows her former other half into the plane. Strangely, this time they don't hold hands.
