'Great to be back in McGonagles' said Bono after I Will Follow, and tonight the 3Arena could have been that fabled Dublin club where the band last played in 1979.
Not that President of Ireland would have been in the audience in 1979. Michael Higgins was here tonight, as was Shane McGowan of The Pogues, 'right in front of you' during Beautiful Day.
Nor would there have been a Brazilian POP-era Bono, in boxing gown and Fly-shades, up on stage to spar with Songs Of Innocence-era Bono in Mysterious Ways... or shoot the band on camera for a global broadcast of Desire.
Nor would there have been pages falling from the rafters during Until the End of the World, pages from Dante and pages providing information on 'Justice For The Forgotten'.
Out of Control was back in the set tonight, along with Desire and Angel of Harlem and what about this for a stat from @U2gigs? Bad tonight was making it's 500th known full performance. Was it ever more spine-tingling, segueuing so beautifully into '40'.

And check out these great reviews of night one in Dublin, including, in The Irish Independent, a mention of McGonagles... and everywhere else in Dublin the band have played.
'Amazingly, this is the Fab Four's first Irish show in the great indoors since New Year's Eve 1989, in the old Point Depot long before this venue received a 21st-century facelift. It is mind-boggling to look back at it now, but their Dublin gigography includes shows in the Top Hat, Dún Laoghaire, the ill-fated Stardust in Artane, McGonagles on South Anne Street, Harcourt Street's TV Club, and of course, the Baggot Inn...'
And in a concert overflowing with highlights,’ added Eamonn Sweeney. 'Sunday Bloody Sunday' segueing into 'Raised By Wolves', a song about the devastating Dublin and Monaghan car bombs of May 1974, is a stunning, jaw-dropping moment. It proves U2 haven't lost their capacity to interpret the tangled history of this troubled isle and continue to ask searching questions. The song concludes with the simple message: "Justice for the Forgotten."
'As an object lesson in how to stir a capacity audience into a lather of sweat, elation and emotion, it's a seamless, effective piece of work,' reported The Irish Times. 'As an example of rock'n'roll theatre – particularly with a powerful and often mesmerising stage show that on occasion punches the weaker tracks from Songs of Innocence into submission – it is superlative.'
The Irish Mirror put it like this: 'Crowd pleasers Vertigo and I Will Follow really got feet stamping as the four-piece went for a more intimate setting for this tour rather than the huge stadium shows they are famous for.
The sound came evenly and cleanly through huge speakers hung on the ceiling throughout the venue.
No matter where you were sitting, the acoustics were astonishing.'
