Tanya Tucker will unite with Elvis Presley’s legendary backup vocal group, the Imperials, for four Christmas shows in December. Joe Guercio, Presley’s former orchestra leader, is producing the show and will conduct Tucker’s band. Billed as Tanya Tucker Family Christmas, the event will include performances by the singer’s two daughters and her niece, according to Steve Lassiter, Tucker’s booking agent. The tour begins Dec. 12 at Harrah’s Casino in Kansas City, Mo., and continues Dec. 14 at Buffalo Run Casino in Miami, Okla., and Dec. 15 at Delta Downs Entertainment Center in Vinton, La., before concluding Dec. 21 at the Wildhorse Saloon in Nashville. The Imperials are also expected to tour with Tucker in 2008.
