As Carl Frampton dominated to become king of the ring, his travelling army of fans made sure they were crowned the number one supporters.
The Belfast boxer (29) came face-to-face with big rival Scott Quigg (27) on Saturday night in the Manchester Arena where both men's undefeated records were on the line.
The city was flooded with fans from Northern Ireland supporting The Jackal in the days leading up to the long-anticipated clash and they cheered him to victory in unifying the IBF and WBA super-bantamweight titles.
The fierce rivalry between the pair reached fever-pitch last week as tensions rose in heated clashes at the final Press conference and the weigh-in, where both Quigg and Frampton consistently claimed they would have the strongest and loudest support in attendance on the night.
If that was a challenge for their fans, it was gratefully accepted as they engaged in a battle themselves of who could make the most noise.
Quigg may have been the home fighter, coming from the outskirts of the city in Bury - but soon the arena felt like it was bang in the middle of Belfast.
As the undercard got under way, hordes of Frampton fans filled the corridors of the arena sending a clear message of how many were in The Jackal's corner.
The sound was deafening as they jumped, danced and sang "There's only one Carl Frampton" loud enough that Frampton himself could hear them in his dressing room - as could Quigg.
As the chants echoed around the arena and its corridors, the fans lived up to the words they were singing: "Everywhere we go, it's the Ulster boys making all the noise."
Naturally, the English fans, who were also out in force, joined in with their own version, but were drowned out.
The electric atmosphere continued as fight fans took their seats to welcome Frampton and Quigg into the ring for the moment of truth.
Frampton was met with an almighty roar as he entered the arena to the haunting sounds of Belfast Child, which then broke in to Run This Town as he walked to the ring - it appeared to many in the venue that he was doing just that.
The fight went the distance of 12 rounds, and just as Frampton didn't relent in his attack, nor did those supporting him.
And their passion and enthusiasm wasn't in vain, as in the champ's post-fight interview he joined in with the singing and branded the travelling fans "unbelievable".
He added: "This isn't Manchester, is it?
"Seems like it is Belfast."
