This will stir the blood. What a moment.
James Connolly was a well respected rugby coach in Cheltenham.
He coached Cheltenham Tigers, Cheltenham North and Cheltenham Saracens, and sadly passed away recently from a brain tumour.
At James' funeral his son led the Haka after more than 1,000 people had lined the streets to say goodbye to his father, and it was an incredible display of affection towards a much-loved figure.
James' cousin Joe, from Tullamore, was at the funeral and told us: "Over 1,000 people attended the church and lined the streets outside the church clapping and cheering as he was leaving the church.
"His son Aaron led the Haka yesterday evening, joined by all his friends and rugby family.
"It was a very moving Haka. James was loved and looked up to by many. I just wanted to share this video with you, I know he would have been so proud of Aaron yesterday."
