Boney M, the 1970s disco group lead by Maizie Williams, was told not to sing one of their biggest hits at a concert in the West Bank on Wednesday. Williams says the Palestinian concert organizers warned her not to sing “Rivers of Babylon.” and she doesn’t know “if it was a political thing or what.” The song’s chorus quotes from the Book of Psalms, referring to the exiled Jewish people’s desire to return to Israel. Palestinians dispute the right of the Jews to return to land they say belongs to them. The organizers told Williams the song is “inappropriate.”
