YOU know a strike's making an impact when one of the world's most famous bands delays its show as a result.
On Monday, outside the Arena, a huge queue snakes around its walls as hundreds complain their tickets haven't arrived.
"The band are delaying their show ten minutes," shouts a member of staff, only to repeat her message ten minutes later.
But the wait's worth it.
Fleetwood Mac – despite vowing they would never play again – play a set of classics, including The Chain, Rhiannon, Go Your Own Way, Don't Stop, Say You Love Me and Sara.
And surprisingly, the band play arguably their biggest hit, The Chain, second.
Delivery is impeccable - the world's most famous bass line sounds bigger and more visceral than its does opening the BBC's F1 coverage.
The line-up includes Mick Fleetwood, John McVie, Lesley Buckingham and Stevie Nicks.
Buckingham and Nicks take their perches at the front of the stage, exchanging glances, smiles and even a cuddle throughout the show.
And, remarkably, despite it being 41 years since the Grammy-winning Rumours was released, Nicks' trademark voice – both whisky-laden and ethereal, is superbly unchanged.
At several points throughout the show Nicks disappears behind the stage, emerging wearing a different shawl or a dress.
Her black and deep red floaty costumes reflect the dual-character of her voice – which is are at once other-worldy, earthy and dark.
Buckingham's on form too, elaborating – perhaps a little excessively – on the guitar solo to Go Insane.
He also shines as a soloist, playing intricate acoustic guitar on softer numbers as the band retreat to the back of the stage.
And then, following his lone performances, Buckingham stands at the front of the stage, lapping up the applause – rightly so.
