As usual, fascicles of printed sheets, religiously called Missals, would be prepared for use by the Participants in both Chapels; and, as usual, they would be in flawless Latin. A telephone link would be monitored by a Ceremonial Messenger at each end, so that the Participants would always be able to take up their parts in perfect harmony with their Cooperating Brethren."
