After a moving speech eulogizing slain Reverend and South Carolina state Senator Clementa Pinckney on Friday, President Barack Obama abruptly broke into song, singing Amazing Grace. He was joined by the congregation memorializing the assassinated civil rights leader at TD Arena, near Charleston’s Emanuel AME, the church where Pinckney and eight others were gunned down during a Bible study.

Obama speaks at the end of the ceremony and starts singing at the 15:24 mark in livestream aired by the Post and Courier here.
