Here are some others, found on a quick trawl of YouTube.
Let me quote Pope Benedict:
Many people who clearly accepted the binding character of the Second Vatican Council, and were faithful to the Pope and the Bishops, nonetheless also desired to recover the form of the sacred liturgy that was dear to them. This occurred above all because in many places celebrations were not faithful to the prescriptions of the new Missal, but the latter actually was understood as authorizing or even requiring creativity, which frequently led to deformations of the liturgy which were hard to bear. I am speaking from experience, since I too lived through that period with all its hopes and its confusion. And I have seen how arbitrary deformations of the liturgy caused deep pain to individuals totally rooted in the faith of the Church.(Letter of the Holy Father, Pope Benedict XVI to the Bishops of the whole world to present the “Motu Proprio” on the use of the Roman Liturgy prior to the reform of 1970)
