Southern California Catholic : Bishop Kevin Vann's Mass of Installation

This past Monday, Bishop Kevin William Vann, previously bishop of the diocese of Fort Worth, TX, was installed by Archbishop Jose Horacio Gomez as the fourth bishop of the Diocese of Orange in California. Bishop Tod D. Brown, Bishop Emeritus now of Orange, has retired at having met the mandatory retirement age given by the church at the age of 75. (Sometimes, it can delay until a bishop if 76 or 77 though).
Bishop Vann, had his Mass at the University of California Irvine's Bren Events Center, which accommodation more than 4000 people, I estimate. The reason for the Mass not being at a church, or Holy Family Cathedral was because the largest church in the diocese only holds ~2200 people, St. Columban, in Garden Grove. Obviously the liturgical planners knew that much more people would come than that. Among those present were the Norbertine Fathers of St. Micheal's Abbey, 200-300 concelebrent priests, and maybe 30 bishops (and 1 abbot). The servers were mostly seminarians from St. John's Seminary in Camirillo. Some bishops (abbot)/priests I recognized were:

Archbishop Jose Gomez, Metropolitan Archbishop of Los Angeles (Main Celebrant)
Archbishop Carlo Vigano, Papal Nuncio to the United States
Archbishop Salvatore Cordileone, new Archbishop of San Francisco
Cardinal Roger Mahony, Archbishop Emeritus of LA
Bishop Kevin Vann, New bishop of Orange (Main Celebrant?)
Bishop Tod D. Brown, now-Bishop Emeritus of Orange
Bishop Cirilo Flores, Coadjutor Bishop of San Diego (I am sure Bishop Brom was also there)
Bishop Gerald Barnes, Bishop of San Bernardino
Bishop Oscar Solis, Auxiliary Bishop of LA
Bishop Edward Clark, Auxiliary Bishop of LA
Bishop Thomas Curry, Auxiliary Bishop of LA
Bishop Alexander Salazar, Auxiliary Bishop of LA
Bishop Gerald Wilkerson, Auxiliary Bishop of LA
Bishop Dominic Loung, Auxiliary Bishop of Orange
Bishop Rutilio del Riego, Auxiliary Bishop of San Bernardino
Abbot Eugene Hayes, Father Abbot to the Norbertines of St. Micheal's Abbey
Fr. Brain Caseneda, M.C. to Archbishop Gomez
A lot of Norbertine priests I know.
