I think Lady Stoneheart ordered the massacre of the religious group. One of the riders seemed to recognize Sandor, so when they went back to the Brotherhood and told her who they saw, she thinks Sandor = Lannisters = anyone remotely tied to the Red Wedding must die, and gives the go ahead for the slaughter. If this…

What about U2's extraordinary, harrowing "Wake Up Dead Man" or the groovy entirety of Jesus Christ Superstar?
