Sing along if you, "Deck your screens with tons of Dolly! Fa La La La La, La La La La La!"
The reason to sing is that CMT and Dolly Parton are planning a Holly Dolly Christmas channel takeover.
During the takeover, there will be a holiday movie marathon, music videos, a countdown, and more.
A Holly Dolly Christmas kicks off this weekend.
What's your favorite holiday tradition?
