Good King Wenceslas

"Therefore, Christian men, be sure, wealth or rank possessing,
You who now will bless the poor shall yourselves find blessing."
--Good King Wenceslas

I used to take piano lessons when I was younger and this was one of the Christmas songs I learned to play on the piano. I always liked it. It's considered a Christmas carol because St. Stephen's feast day was celebrated on the 26th of December.
