The graduation anthem, Gaudeamus Igitur accompanies the title sequence to this guided tour of the two university cities, first Oxford then Cambridge, and also the Cambridgeshire village of Grantchester. In Oxford the students carry their caps and gowns in the street to avoid breaking college regulations if they choose to smoke, and in Cambridge we learn that on many maps the river changes its name at the Silver Street Bridge and is called Granta above and Cam below it.
