To kick off the start of Coog Radio’s Blog-vent Calendar, we present to you a musical performance by Jimmy Fallon, Horatio Sanz, Chris Kattan, and Tracy Morgan. The classic Christmas song’ll sure bring some cheer as the countdown to finals begins. But don’t you worry, there’s 24 days left until Christmas — and 24 more songs left on our blog-vent calendar. Come back tomorrow to see what our blog-vent calendar has in store. Happy holidays!
