On the 2007 re-release of my holiday collection, I added a wintry posthumous duet with Dean Martin. Who the heck is that? Ans: Martina McBride. (The song was "Baby, It's Cold Outside.") Martina McBride attends The Judds Love Is Alive The Final Concert hosted by CMT at Murphy Center at Middle Tennessee State University on November 03, 2022 in Murfreesboro, Tennessee.
