This traditional song from Puerto Rico, spiritedly arranged by Cristian Grases, is usually sung at Christmas time. A group of singers would knock on the door of a neighbor or friend's house and ask them to open the door so that they can come in and celebrate together! The tuneful melody and playful syllables embody the joy of the local culture. Excellent for high school and college treble choruses.
