美国独立音乐人彼得‧荷兰斯（Peter Hollens）是一位清唱歌手。在最新录制的MV中，他独自坐在教堂里演唱一首圣诞歌，视频发布两周，已获400多万次点阅、2万多听众点赞。

这首歌曲《玛丽，你知道吗？》（Mary, Did You know?）的歌词由马克‧劳利（Mark Lowry）创作于1984年，六年后由巴迪‧格林（Buddy Greene）谱曲，1998年被盖瑟人声乐队（Gaither Vocal Band）收入圣诞专辑。此歌并且被肯尼‧罗杰斯（Kenny Rogers）等歌手翻唱，成为一首新世代的流行圣诞歌曲。

荷兰斯推出的版本采取“声部渐入”的手法，最多同时有六个声部合唱，视频也进行了影像合成，效果真的很动人。

Mary, Did You Know?
歌词作者： Mark Lowry

Mary, did you know
that your Baby Boy would one day walk on water?
Mary, did you know
that your Baby Boy would save our sons and daughters?
Did you know
that your Baby Boy has come to make you new?
This Child that you delivered will soon deliver you.

Mary, did you know
that your Baby Boy will give sight to a blind man?
Mary, did you know
that your Baby Boy will calm the storm with His hand?
Did you know
that your Baby Boy has walked where angels trod?
When you kiss your little Baby you kissed the face of God?

Mary did you know.. Ooo Ooo Ooo

The blind will see.
The deaf will hear.
The dead will live again.
The lame will leap.
The dumb will speak
The praises of The Lamb.

Mary, did you know
that your Baby Boy is Lord of all creation?
Mary, did you know
that your Baby Boy would one day rule the nations?
Did you know
that your Baby Boy is heaven’s perfect Lamb?
The sleeping Child you’re holding is the Great, I Am.
