In the bitter cold of Scotstoun Stadium, Saints produced a performance and a result to warm the hearts of their supporters.
Plenty had made the trip up to Glasgow, perhaps more in hope than expectation.
Or perhaps it was just because Glasgow is a good night out.
But whatever they came for, they were rewarded by a group of players who simply refuse to fret about reputations.
Glasgow, as the likes of Leinster and Ulster have in recent years, adopted the favourites tag for this Champions Cup clash with Saints.
And Glasgow, as the likes of Leinster and Ulster have in recent years, found themselves outplayed and outfought by Jim Mallinder’s men.
When it was said they wouldn’t get a result in Dublin, they did.
And when it was said they wouldn’t get a result in Belfast, they did.
And history repeated itself at Scotstoun.
Glasgow, the Guinness Pro12 champions, let us not forget, had won their past six matches when hosting an English side in clup rugby’s premier European competition.
Saints had suffered at their hands before, conceding a late Peter Horne try as the Warriors snatched victory in January 2013.
But then Saints needed a victory and a bonus point to progress to the quarter-finals.
This time, they just wanted to back up their opening-night success against Scarlets.
And, as it unfolded, they were to do it in some style.
Every single player who put the shirt on contributed in a positive manner.
From Alex Waller at No.1, to Ben Foden at No.15 - Saints were superb.
It was the team performance they have been craving in the formative stage of the season as the forwards stood tall and the backs broke down the Warriors wall.
It was the performance Saints fans knew their side could produce - those nights in Dublin and Belfast being the evidence.
But with those matches so far back (and a few pints drunk after them blurring the memory a little), they sought a reminder.
And they got a striking one in Glasgow on Saturday night.
Saints now sit top of Pool 3, with the potentially decisive double-header against Racing 92 to come next monnth.
That is all that could be asked from the players, but the fact they also denied Glasgow a losing bonus point on their own turf is a fantastic fillip.
Saints deserved everything they got from their trip to Scotstoun.
And they certainly earned the celebratory post-match pints.
Now they will look to take the momentum into Aviva Premiership matters and put right their lowly league standing.
But, for now, that is for another day.
First, it is about savouring a special display in Glasgow.
And savouring another one of those special European nights involving Northampton Saints.
