Sad Lullaby" is a world-famous lullaby. In 1969-1970, UNESCO expert and ethnomusicologist Hugo Zemp recorded a number of local songs, which appeared on an LP released in 1973 as part of the UNESCO Music Resources Collection. One of the songs is called "Rorogwela Lullaby", sung by an old mother named Afunakwa from the Baeggu tribe in the Solomon Islands. It was later used as a single in the "Deep Forest" album released in 1992 by the French world music group Deep Forest, which caused a worldwide sensation. The general idea of ??the song is that a child is crying because he can't see his parents. His older brother sings this song to comfort him, telling him that his parents have passed away, but he is still by his side to protect him
