Because this is a copyrighted song, I can't post my arrangement here. However, if you'd like to learn this arrangement, contact me for a Skype lesson and I can show you how to play it.
Also, check out my book of Christmas songs arranged for solo guitar HERE. Note that "THE CHRISTMAS SONG" is NOT included in this book. The songs arranged in my book are all public domain. I'd like to publish a book which included copyrighted tunes as well, but the publishing costs are prohibitive for my budget. Songs I arranged in my book are:
Silent Night, Away In A Manger, Jingle Bells, God Rest Ye Merry Gentlemen, It Came Upon A Midnight Clear, The First Noel, We Three Kings, O Holy Night, We Wish You A Merry Christmas, O Come All Ye Faithful, Joy To The World, Angels We Have Heard On High, O Little Town Of Bethlehem, and Hark The Herald Angels Sing.
