The best performance of this wonderful song that I ever heard does not even belong to Frank Sinatra (sorry, Frankie!) but to my local church choir. Performed acapella, it sounds so elevated and serene! I am going to work as the accompanist and play We Wish You the Merriest with the school choir for Christmas and I can't wait to do it! Printed off the arrangement here and it looks very nice taking into account I'm an early mid-intermediate yet.
