Shown on New York’s WPIX-TV, and syndicated to local stations across the country, this is the “original” Yule Log show – well, as original as it gets. (The tradition was begun on TV in 1966, but new video, at a different location, was reshot in 1970.) But the vintage carols and holiday pop songs are what turn this seven-minute video loop into hours of musical entertainment. Turn on the high-def TV, turn up the volume, and warm up to this four-hour Christmas Day special. T
