Here is a curious little film produced by the University. It starts with footage of the bells being lifted into the tower in the autumn of 2010, and an interview with the main donor who paid for them. Then there is footage of the religious ceremony which marked their installation. Finally, from 7:00 is footage of the bells being rung.
