From Romania to El Salvador to the Pacific island Kiribati, it turns out you don’t have to be in Utah to join in the chorus of the famed Mormon Tabernacle Choir.

The 360-member choir, renowned for its gorgeous performances of church music, put out a call for guest vocalists, who could submit their renditions of “Hallelujah” via YouTube video. More than 2,500 videos came pouring in.

In a beautiful performance, the volunteer choir and its accompanying 150-member symphony sang along with all of those videos.

Greg Droubay, a spokesman for the choir, said that the choir posted online a recording and the sheet music for each vocal part in the famous “Hallelujah” chorus from Handel’s “Messiah.” Mormons and other enthusiastic singers learned from the instructional videos and posted their own contributions.

Among those who participated: the country group Firefly, actor Donny Osmond, Utah Gov. Gary Herbert and choirs of several Christian denominations from around the world.

The Mormon choir put all the videos together, then performed along with them in the grand Salt Lake Tabernacle.

The resulting video is meant to promote the Mormon Tabernacle Choir’s new performance of the entirety of George Frideric Handel’s “Messiah.” The full performance will air live online at 9:30 p.m. Eastern time on March 25, Good Friday.
