The song Little Drummer Boy can be great or it can be very bad. Have heard some pretty crappy version of this song many times. Over the years I have only heard three version I have liked. Which are, Boney M, Celtic Woman and Sean Quigley. Well now there is a fourth one to add to the list. It is Pentatonix version. Have never hear of this group. So after hearing this song I check out there other work. They do some very cool cover version and their own songs. Check out here take on the song > here or below.
