Gaudeamus igitur

In the last video, of Cardinal Ratzinger receiving an honorary doctorate, you hear the choir singing a song. It's in the tune of Gaudeamus Igitur, though the lyrics sound different (and rightly so too, I think):

Gaudeamus igitur.
Juvenes dum sumus.
Gaudeamus igitur.
Juvenes dum sumus.
Post jucundam juventutem.
Post molestam senectutem.
Nos habebit humus —
Nos habebit humus



From Wiki:
"De Brevitate Vitae" ("On the Shortness of Life"), more commonly known as "Gaudeamus Igitur" ("Let Us Rejoice") or just "Gaudeamus", is a popular academic commercium song in many European countries, mainly sung or performed at university graduation ceremonies. Despite its use as a formal graduation hymn, it is a jocular, light-hearted composition that pokes fun at university life. The song dates to the early 18th century, based on a Latin manuscript from 1287.[1] It is in the tradition of carpe diem ("seize the day"), with its exhortations to enjoy life.

It was known as a beer-drinking song in many ancient universities, and is the official song of many schools, colleges, universities, institutions, and student societies.

Latin	English
Gaudeamus igitur Juvenes dum sumus. Post jucundam juventutem Post molestam senectutem Nos habebit humus.	Let us rejoice therefore While we are young. After a pleasant youth After a troubling old age The earth will have us.
