So, over at the Lion Guard wiki some members have been uncovering some early concept stuff. In addition to finding the Zuka Zama concept song (which is all over the place now) the same member found five different concept videos containing Kion's Lament (early/demo singer), Tonight we Strike (two versions), Call of the Guard and the original ending for RotR:

I have to say, I think I prefer the very early version of Tonight we Strike to the final. I love how those birds fly out from behind him.
