According to Yoon Sang, the musical director for the South Korean artists, "Belated Regret," a South Korean ballad released by sibling duo Hyeonee and Deokee in 1985, was reportedly the most well received song at the concert held at the 1,500-seat East Pyongyang Grand Theatre. The song, which was not in the initially agreed set list, is believed to have been performed at the request of Kim.
