Here's one collected from oral tradition:
THE SONS OF LEVI

Come all ye knights, ye knights of Molites
Come learn to do as I have done
You might have seen the armour brighter
Within the New Jerusalem

We are the true-born sons of Levi
We are the true-born sons of God
We're the root and branch of David
The glorious bright and morning star

Moses planted Aaron's rod
In one night the rod did bud
Moses smote the Egyptian waters
And that very night they turned to blood

When Joshua and I crossed over Jordan
When Joshua and I crossed over home
The seven trumps and the ram's horn sounded
Sounded loud before the throne

We are the true-born sons of Levi
We are the true-born sons of God
We're the root and branch of David
The glorious bright and morning star
