No, McGrath of Harlow, I am not just taking the piss. I honestly believe that
1. a reasonable person, seeing or hearing that stanza of LotD, and not having Carter at his shoulder to disabuse him of the notion, could very well be convinced that the "they" who hung Jesus on a cross were meant to refer to the holy people who said it was a shame he danced on the sabbath,
2. "holy people" is a reference to, if not the entire Jewish people of the time, then to a segment thereof - maybe the Pharisees, maybe the Sanhedrin, maybe the priests, maybe some other Jewish authorities, but, in any event, definitely not to the Romans,
3. it is a lie, and, historically, a horrendous lie, to say that the Jews, or the Pharisees, or the Sanhedrin, or the priests, or any Jewish authorities, legal or religious, hung Jesus on a cross.

As to whether anyone agrees with me, I'm not sure what difference that makes, but I hope that George will report back with the results of the experiment to see about the first point above. Those who are sure that no one agrees with me may also wish to conduct the experiment.
