Richard III and GKC

OK, this is old news, but I just discovered it a few minutes ago, so that is why I hadn't posted it before.

The remains of Richard III (king of England from 1483-1485) were discovered in 2012, and earlier this year (in March) they were reburied Leicester Cathedral. But what I had not known till just today was an interesting bit of news in connection with GKC concerning the service of reburial:

The coffin remained shouldered as the eulogy was read, and the cathedral procession then led the bearer party to a plinth in front of the altar, where it was laid. The opening prayer, from the Dean of Leicester, the Very Revd David Monteith, was from the medieval rite of reburial, and the opening hymn, G. K. Chesterton's "O God of earth and altar", arranged by Vaughan Williams, contrasted the imperfections of earthly life ("not least as exemplified by our faltering rulers", an explanatory note suggested).
