I am 63 years old, and I have always been a Roman Catholic. Daily Mass, which is the basic Mass without the singing, collections, and shorter sermons if any, usually runs around half hour. I hardly remember too many times when Mass lasted longer than an hour, even pre Vatican II. But when it did go longer, it usually was because the priest either spoke for more than 25 minutes, or other business was conducted at the Mass, such as Baptisms. The vigil Mass for Easter Sunday is always long.
As an RC convert who attends a church planted under the Pastoral Provision, our service is more like 90 minutes because we do the full Roman Canon version of the Eucharist, there is a LOT of chanting, and that’s just the way the people who came from the Episcopal church and started it wanted it.
Our Cardinal came for the first time ever a while back (our first Cardinal ever too!). He was moved and impressed by the attention to the liturgy. He said he hoped we former Anglicans could teach the Roman church something about liturgy and music, and that the Roman church, in return, could teach us something about Obedience. :)
