South Korean musicians who will perform in Pyongyang in April are expected to sing songs that are well known to North Koreans as well as a few North Korean numbers, industry watchers said Sunday.

The South's art troupe will make a four-day trip to Pyongyang from March 31 for two performances, respectively on April 1 and April 3, ahead of an inter-Korean summit slated for late next month.

The set list for the concerts will mainly consist of South Korean musicians' songs that are well-known to North Koreans or that could appeal to people in the North, they said.

Some North Korean songs are likely to be sung as well, as the upcoming concerts reciprocate a North Korean art troupe's performances in South Korea to celebrate the PyeongChang Winter Olympics last month.

Contemporary Korean pop legend Cho Yong-pil and Lee Sun-hee, who previously performed in Pyongyang in the 2000s, are expected to sing their hit songs.

Cho, who held a solo concert in the North in 2005, will likely sing "The Cafe in the Winter," known to be one of favorite songs of late North Korean leader Kim Jong-il, and others including "Dear Friend" and "Dream."

Lee, who traveled to the North in 2003 for a joint concert, will sing her hit songs such as "To J," which was performed by North Korean musicians last month in the South.

Pop diva Baek Ji-young is expected to sing ballads including "Like Being Shot by a Bullet," and "Don't Forget."

The five-member girl group Red Velvet will likely sing "Red Flavor," "Bad Boy," and "Peek-A-Boo."

South Korea has agreed to send a 160-member art troupe, including eight musicians and one girl group, but more could be added to the list due to a planned joint performance slated for April 3.

An advance team for South Korea's art troupe recently consulted with the North on adding South Korean rapper Psy to the art troupe, but the two Koreas have yet to reach an agreement. Psy rose to international stardom with his global mega-hit "Gangnam Style."
