My favorite Christmas carols are "Carol of the Bells," especially the Trans-Siberian Orchestra version known as "Christmas in Sarajevo;" "Do You Hear What I Hear," especially Bing Crosby's version; "Hark the Herald Angels Sing," and "Little Drummer Boy/Peace on Earth" by Bing and David Bowie. I also love "Grandma Got Run Over By A Reindeer" and "The Twelve Pains of Christmas." :-)
Mom's favorite is "What Child Is This." Dad's is "O Holy Night." Grandma Doyle's (Mom's mom) was "Little Drummer Boy."
