Only most. I don't think I've ever previously encountered the third verse of It Came Upon a Midnight Clear. It speaks of the woes of sin and strife, of a world that has suffered long. It says we've endured 2,000 years of wrong: "And warring humankind hears not/The tidings which they* bring" Then it tells us:
O hush the noise and cease your strifeHow have I missed out on this motherly command all these many Christmases of my life?
And hear the angels sing;
*the angels bending near the earth
Must be something about third verses. We also sang the third of Joy to the World and it also has a surprising turn. It speaks of thorns that infest the ground and blessings that flow "far as the curse is found."
