I have such a critical spirit, however I do love the missing verses. Here they are, if anyone is interested.
"Yet with the woes of sin and strife
The world hath suffered long;
Beneath the angel-strain have rolled
Two thousand years of wrong;
And man, at war with man, hears not
The love song which they bring:
O hush the noise, ye men of strife,
And hear the angels sing.
O ye beneath life's crushing load,
Whose forms are bending low,
Who toil along the climbing way
With painful steps and slow;
Look now, for glad and golden hours
Come swiftly on the wing;
Oh rest beside the weary road
And hear the angels sing"
