I loved that PEACEFUL chant. It reminded of the beast rally in The Island of Doctor Moreau : “What is the LAW?” “Not to walk on all fours.” “Are we not men?”
‘course I’m thinking of the 1933 adaptation, THE ISLAND OF LOST SOULS, with Charles Laughton and Bela Lugosi.
How about the endless "F you"? That seemed to be chanted mostly in female voices.
