SEOUL, Feb. 25 (Yonhap) -- South Korean rapper and global star Psy performed "Gangnam Style" in front of hundreds of thousands of people in Seoul before the inauguration ceremony of President Park Geun-hye on Monday.
He fired up the pre-ceremony show by singing "Champion" and "Gangnam Style," a global hit in 2012, and dancing his trademark horse-riding moves for the latter song.
"I'm going to sing a song that allowed me to experience great joy and miraculous things. As a citizen, I hope joyful and miraculous things will happen to all of you from now on," he said before performing "Gangnam Style."
The star then asked the attendees to stand up and do the horse dance together with him, turning the otherwise usually calm and solemn inauguration into a cheerful festival scene.
The artists who performed at the pre-ceremony event included K-pop boy group JYJ; pop divas Jang Yun-jeong and Insooni; Kim Deok-su, who played samulnori or traditional Korean percussion music; and musical performers such as Nam Gyeong-ju and Sonya.
The singers performed popular songs that represent each decade of Korea's modern history.
K-pop group JYJ represented the 1990s, singing the famous songs of Seo Taeji and Boys, and YB's "Oh, Victory to Korea," a hit song of the 2002 World Cup co-hosted by Korea and Japan.
Cast members of KBS 2TV's comedy show, "Gag Concert," took important roles both as performers and co-hosts of the pre-ceremony event. Comedians from the show's "Brave Guys" series staged a special performance.
A 300-member choir composed of ordinary citizens as well as 120 college students majoring in musical plays also performed alongside the famed celebrities.
During the ceremony in which Park was sworn in as president, soprano Sumi Jo sang the national anthem with baritone Choi Hyun-soo.
It was one of the biggest performances for a presidential inauguration ceremony in the country's history. Officials estimated 70,000 people attended the ceremony.
Park is set to officially begin her work as the country's 18th president after the ceremony.
