The group's Crystal Hoyt makes an appearance as a sexy Mrs. Claus while the trio's Butter shows up in 'holla'-day attire. There's also an antlered, red-nosed rein-cow. You just have to see it to believe it.

Written by Butter and co-produced with Toby Keith, "Rockin The Beer Gut ('Holla' Day Version)" is a hilarious re-working of the group's country hit, complete with new lyrics and the addition of a children's chorus. The song is available now at all digital retailers, including iTunes and Amazon.com.

The Show Dog Nashville band is performing it at all of their concerts this holiday season, including upcoming shows in St. Louis (12/8), Greeley, Colo. (12/9), Tampa (12/18) and Nashville (12/19). You can also check out their special 'holla'-day segment on CMT's Hazel's Southern Fried Flicks premiering on Dec 12 and re-airing on Dec. 13 (check local listings for times and channel). - Check out all the fun right here
