Remember when Christmas was reserved for December? And then the merchandizers pushed it back to the day after Thanksgiving. In recent years, it has started about Hallowee. Now comes word from John Rook that Clear Channel's KEFM in Omaha, Neb., started programming an all-Christmas format Friday (Sept. 23). As the song sez, laments John: "Christmas comes just once each year" -- September, October, November, December and the first two weeks of January. Sad but true.
