Eamonn Kilbride (46) was performing the energetic dance by Korean popstar PSY at the Thwaites Brewery party in Lancashire, London when he suddenly fell to the ground.
His wife Julie, who was there celebrating her birthday, tried to perform CPR but to no avail. He died of acute heart failure.
Kilbride said that her husband was “a great family man” who she had been married to for 23 years. “He said he had a bit of a pain and just collapsed,” she said.
