2. Mendelssohn - Hark The Herald Angels Sing
Did you know that the chorus of this classic carol was originally going to be, "Hark! How all the welkin rings / Glory to the King of Kings"? And its lyricist, Charles Wesley, originally wanted some slow and rather depressing music to accompany it? Thank goodness Mendelssohn stuck his oar in with his superb melody.
