Anyone ever heard?

Of Andrew Peterson? He writes books and songs. Looks like the book is new, but he's been writing songs for a while. My sis just mentioned a song of his tonight and I am intrigued. The song is Matthew's Begats, and it is on iTunes. I haven't heard a song about the begats before, but I think I like it. It has a little banjo thrown in to add to the appeal. The other stuff there sounds very cool too. The sample of O Come, O Come, Emmanuel was awesome classical guitarish stuff as well.

 BTW, grandma has always referred to her sisters as "my sis Edna" or "my sis Ruby." So there you go, Sis.
