"I had the idea of doing a Christmas version of 'Home,'" Blake tells CBS Local. "Because the song would kind of lend itself to the holidays anyway. That's when you really miss home. I felt really stupid asking that question because he is Michael Buble."
Blake says the Canadian-born singer was "excited he had a country hit as a songwriter" and recalls that the two had sung the song together a few times at Michael's concerts.
"We filmed a David Foster special together where we sang the song together," he adds.
Obviously, the two found harmony outside of the Yuletide duet. Michael joined Team Blake as a mentor on this season of the hit NBC singing competition, "The Voice." They'll also perform the song together on Michael's "Home for the Holidays" special, airing Dec. 10 at 10:00 PM ET on NBC. That's exactly one week after Blake's "Not So Family Christmas Special," airing Dec. 3, also on NBC.
