The four-member music combo Boney M, who became a disco legend of the 1970s, made a visit to a demonstration denouncing China's repatriation of North Korean defectors in front of the Chinese Embassy Wednesday evening.

The group lit candles together with protesters.

Boney M lead singer Liz Mitchell sings during a candle-lit rally held to demand China stop repatriating North Korean refugees, near the Chinese Embassy in Seoul on Thursday.

Boney M still have a wide range of fans around the world because of hit tracks like "By the Rivers of Babylon," a song dedicated to freedom for the oppressed. Boney M sang "Let It Be" and "My Life Is in Your Hands" at the protest site.

The group has several concerts scheduled in Korea until the end of April and plans to donate proceeds from its concert in Seoul this weekend to help further the cause.
