Near the start of our work entitled Mem., reworked for the stage of The Place Theatre in Euston in 2004, The Five Andrews attempted a sustained scream. This lasted under a minute as I recall, although audience members may have memories of the event lasting longer.
We could try it again if the public demands it by simple majority in a referendum.
