On Friday, November 10th the KOST 103.5 family gathered for our annual #KOSTChristmas Flip Party to celebrate the launch of nonstop Christmas music on KOST! Our staffers came decked out in their best ugly Christmas sweaters and enjoyed delicious Holiday treats like cake pops, hot cocoa and gingerbread cookies.


All of your favorite KOST jocks were front and center as Santa flipped the switch that played the first Christmas song of the season - Barry Manilow's "Happy Holidays."

Watch the big moment below!
