+Candles in the window
+Shadows painting the ceiling
+Gazing at the fire glow
+Feeling that gingerbread feeling
+
+Precious moments, special people
+Happy faces, I can see
+
+Somewhere in my memory
+Christmas joys all around me
+Living in my memory
+All of the music, all of the magic
+All of the family, home here with me
