Interesting suggestion for an all night “Catholic fest”. You may find the Vigil Masses for both Christmas and Easter come close to your dream scenario there. They aren’t all night, but do go for a good 3-4 hours.

I live up here in the North Georgia Mountains. If Mass lasts more than 60 minutes, the church leaders call the Archbishop in Atlanta and complain. We lost a of good holy Priest that way.

My parish in San Antonio did the Easter Vigil with the whole shebang - seven Old Testament readings, seven Psalms (all the verses :-), multiple Epistles, large groups of RCIA catechumens/candidates.

It would last from about 8:00 p.m., starting with outdoor music before the fire-lighting, until 3:00 or 4:00. (Official bathroom break at least once.) There was always a very good turnout, if not a full church. When the service finally ended, we'd eat and drink on the doorstep until time to set up for the Easter morning Mass. Cops would stop by for snacks.

I've never, in ... 2008-1993 ... 15 years as a Catholic been in another parish that did this. They always cut the readings, and I think that's just wrong.
