After Thursday's win over Estonia, there were softly-spoken whispers that Northern Ireland's famous Green and White Army had lost its voice.
After a gruelling 2018 that brought just two wins from nine fixtures, the usual deafening noise had been conspicuous by its absence for the most part of Windsor Park's first international of the new year.
Fast forward three days and it was back.
There's little doubting the cacophony of noise has an impact on both sets of players, Belarus goalkeeper Andrei Klimovich pressured into hoiking a kick into the stand on more than one occasion on Sunday evening while George Saville admitted afterwards that the home players were given an 'extra push' by the support.
As the players took to the pitch, the roar of 'Green and White Army' was louder than anything heard during the win over Estonia and was a reminder of what it's really supposed to be like at Windsor.
The tone had been set and the fans lived up to their own billing, booing every period of sustained pressure enjoyed by the opposition, roaring home Jonny Evans' opener and responding to Belarus' fortunate equaliser the only way they knew how; by turning up the volume as soon as the ball hit the net.
If anything summed up the attitude of the home support, it was that moment. It would be easy for heads to drop - on the pitch and in the stands - but before Northern Ireland had even kicked-off the restart, the fans were up and louder than ever. In that arena, it's impossible for players not to be lifted.
And just when it appeared it would be a frustrating evening all said and done, Josh Magennis made the Kop erupt as the famous home end sucked the substitute's 87th minute effort into the net - just reward for the efforts by all concerned.
If there had been any doubt on Thursday, the GAWA responded on Sunday.
