The Mormon Tabernacle Choir’s Christmas concerts will have a British flair yet again. Following his countrymen Martin Jarvis, Jane Seymour, Michael York, Claire Bloom and Angela Lansbury (not to mention Irish actor Roma Downey and Welshman John Rhys-Davies), actor Hugh Bonneville — best-known for his six seasons as Robert, Earl of Grantham, on “Downton Abbey” — will narrate this year’s shows.

What will his role in Salt Lake City entail? “I know it’s always a surprise, but I can say it will be pretty epic,” Bonneville said in a phone chat from his home “in the lush, green, usually damp countryside” of West Sussex. “It will be very touching and uplifting and will project a great reminder of the seasonal spirit.”

His friends York and Jarvis helped persuade him to take the gig; Jarvis called the experience “overwhelming, in a good way,” Bonneville recalled.

The Cambridge-educated actor has appeared in films including “Notting Hill,” “The Monuments Men” and the two “Paddington” movies. He recently signed on as host of “From Vienna: The New Year’s Celebration” on PBS’ “Great Performances.”

“I can only describe it as a complete plunge into the unknown,” he said of the yearly special that features the Vienna Philharmonic and Vienna State Ballet. “I’m a blank canvas, plunging into my research, getting material together so I appear vaguely knowledgeable.” His role as host will be to “introduce and put into context great items of music and dance. This is a musical celebration that draws people together.”

Guest vocalist on the Tabernacle Choir concerts will be Sutton Foster, winner of Tony Awards for her roles in “Anything Goes” and “Thoroughly Modern Millie.” Her other Broadway credits include “Little Women,” “The Drowsy Chaperone,” “Young Frankenstein” and “Shrek the Musical.” She currently stars in the TV Land comedy-drama “Younger” and has made guest appearances on series as diverse as “Sesame Street” and “Flight of the Conchords.”
