He said he has been impressed with the commitment of the choir's 300 volunteer singers, most of whom are not professionals.
And Hobbs said he and other Mormon church leaders in Oklahoma are thrilled that Jessop agreed to lead the group.
“That is an incredible coup,” Hobbs said.
“It was exactly the kind of seed we need to get people motivated.”
Meanwhile, while the core of the choir is made up of nonprofessionals, several special guests with professional backgrounds will participate in the program. They include soprano Lisa Howard and baritone Anthony Eversole.
Hobbs said while the concert is free, tickets are required for guests age 8 and older.
He said the public is encouraged to obtain tickets as soon as possible.
For those unable able to obtain tickets, Hobbs recommended they show up at the concert anyway because there will be some standby seating available.
Hobbs also said the concert will be aired Dec. 23-25 on KSBI-52.
