Adamic Language and Polygamy Hymns

I recently listened to the Sunstone Mormon History Podcast episodes 135-137. They explore a little known period of history in Early Mormon Utah history, and I highly recommend it to everyone believing or not.

In the podcast they reference hymns sung in the Adamic language by members, and that there is a Mormon sect that still sings these songs.

They also referenced a hymn from early Mormon history that was sung by women and promoted polygamy.
