As we enter the holiday season, shows often spend time focusing on those who were naughty (because they result in better stories). Karlson and McKenzie, WZLX, Boston came up with an idea that focuses on those who are nice. They’re taking calls from listeners who’ll tell the show about someone they know who’s been nice in the past year (to play off the “naughty or nice” theme). Then, they’re having their very funny co-host, Heather, call that person to give them some holiday cheer by having her sing a Christmas Carol to them. They’re calling it “Heather’s Dial-a-Carol”.
