Bing Crosby's Do You Hear What I Hear

I used to run a paper route in high school and drive around a small town at age 14 early early in the mornings. The country station would play Christmas songs a lot before the regular song rotations would start that sprinkled a Christmas song every half hour or so.
This is one of my favorites that they played every morning.
Yep, good times, a 1970 something green pinto station wagon, full of papers, single digit temps, and me running around the town before I had my license with the town cop's blessing because he was cool like that!
