On Sunday, two LDS general authorities will preside over the 30th anniversary commemoration of President Spencer W. Kimball's revelation that the faith's priesthood will become available to all worthy males. Elders Earl S. Tingey and Sheldon F. Child will preside at the 7 p.m. fireside in the Tabernacle on Temple Square. It will be the first time LDS leaders have presided at a church-sponsored event commemorating the revelation.

Music will be provided by Alex Boye of the Mormon Tabernacle Choir and a multicultural choir under the direction of Mack Wilberg.

Tickets are required for admission to the Tabernacle, but they are no longer available. A church spokesman said overflow seating will be made available on Temple Square for those who wish to attend.
