I have a memory that when Pope John Paul visited in 1982, the group Pro Ecclesia et Pontifice (does it still exist?) decided to show its attachment to the Holy See by serenading the Holy Father the whole night outside the then Apostolic Delegation with traditional Catholic hymns. Eventually, at some ungodly hour, the Pope had to appear at a window and beg the people to go to bed and let the poor Pope get some sleep.
The Knights' vigil is prudently set to end at 8.30pm, by which time the Holy Father should have caught up on the latest episode of Eastenders, and be settling down for a mug of Horlicks and a game of Scrabble with Mgr Georg.
Some twenty years ago, I heard a story in Rome, from an official then high up in the Secretariat of State, which is presumably true. General Noriega, the dictator of Panama, having recently fallen from power, famously holed up in the Apostolic Nunciature, claiming sanctuary, or something of the sort. The Nunciature was promptly surrounded by hordes of gum-chewing GIs with guns trained on every window. Their war of attrition was prosecuted by loud American rock music (BAWN in the USA and the like) being directed at the Nunciature round the clock from powerful loudhailer systems.
In insomniacal desperation, the Nuncio contacted the Vatican Secretariat of State, and some high-up there telephoned the US embassy to the Vatican, threatening to send the Sistine Choir to sing under his windows unless the rock music was silenced.
There was tranquillity in Panama within the hour.
The Pope may not have many divisions; but he has got the Sistine Choir!
