May 12, 2013 seems like a long time ago now.
A lot has happened since then: two Premiership finals, one Amlin Challenge Cup showpiece, plenty of water under the bridge.
But at Allianz Park on Sunday, it felt like time travel had been made possible as Saints transported their fans back to that barnstorming day in Barnet.
In a first 40 minutes every bit as good as the 27-13 Premiership semi-final win against Saracens a year and a half ago, Saints slaughtered their hosts.
It was a systematic dismantling of a team famed for their powerful forwards and their wolf pack defence.
Here, the wolves were mauled as Saints swarmed over them, scoring three first-half tries on their way to a memorable 31-24 success.
While Saracens slipped and slid on the artificial surface, Saints displayed a sure-footed game plan, led by Dorian West’s well-drilled pack.
Behind them, Lee Dickson and Stephen Myler, two men unfortunate to be overlooked by England, used the possession astutely, putting the ball in all the right areas.
Dickson’s assist for James Wilson’s first try was a thing of beauty, the kind of skill shown by a footballer providing an open goal for a team-mate.
And Myler’s boot was also a source of points as he landed kick after kick on a day when opposite number Charlie Hodgson stuttered.
Saints, as they did in May, 2013, enjoyed a 17-point half-time lead.
And though they didn’t quite match the 14-point winning margin of the play-off encounter, they stood tall to secure success that means so much.
It provides a welcome boost after the surprise defeat to Exeter nine days earlier and it puts Jim Mallinder’s men back on top of the Premiership pile.
They are there because they can cope with testing conditions like the Allianz Park monsoon.
They are there because they don’t let a setback linger.
And they are there because they have a unit that, when all parts align, is hard for anyone to stop.
A penny for the thoughts of England boss Stuart Lancaster, then, because how he would like the same right now.
Should he want a bit of the Saints slickness and spirit, he should take another look at a number of their players.
Myler, Dickson, Luther Burrell, Calum Clark, Alex Waller... the list goes on.
These men have proven their quality over and over again in the biggest games, and Saints know just how lucky they are to have them.
At the moment, they are feeling extra fortunate, having anticipated that there would be more than just three of their number wearing white and red this autumn.
And credit must go to the players for not allowing their omission to affect them.
These players have grown with Saints.
This is a team that has come such a long way since last spring’s heroics at Allianz Park.
No longer are they plucky underdogs capable of biting back.
They are a team that has made performances like this one an extremely handy habit.
