This is a recording of the song "Pastores a Belén, sung by other children. It is not the same way we sing it in chorus. They sing the English translation first, followed by the original Spanish lyrics. We sing it the opposite way, beginning with the original Spanish lyrics. There are other aspects of the arrangement that are also different, such as the length of time of the introduction and interlude. However, it is a nice recording, and I thought you might like to listen to it.
It might take a while for the song to load the first time, especially if you have a slow (dial-up) Internet connection. Please be patient, you can do something else while it is loading.
