Psy led thousands of fans at an outdoor concert in Gangnam on Wednesday as they cheered for the Korean national football team in a match against Russia in the 2014 FIFA World Cup in Brazil.
Dressed in red, Psy sang several hit songs and ended his 45-minute performance with "Gangnam Style."
He didn't sing his newest "Hangover," explaining, "I can't possibly sing 'Hangover' while cheering for a football team. It just doesn't seem to be a good fit. We have to stand up straight and do what we need to do. Our cheers must reach the other side of the globe."
He ended on an enthusiastic note, saying "Perhaps we could meet again as we never know if good luck is in store."
