Here's the song from The Library of Congress American Memory Collection, which Nutty posted the link to above:

REMEMBER THE POOR
J. M. Kieffer, 1872.

1. Oh! bright is the fire on the hearthstone tonight,
And sweet are our echoing songs.
The hours bring delight when fond hearts reunite
And music the pleasure prolongs;
But we'll not forget those who sorrow tonight:
The gentle, the loving, the true,
Whose hearts ne'er unite in the strains of delight,
Whose voices a song never knew.

CHORUS: Remember the poor. (Remember the poor.)
The cold world (the cold world) cannot know (cannot know)
All the sunniest hearts (all the sunniest hearts) may endure (may endure)
When hope's ruby glow has been darkened by woe.
Remember, remember the poor.

2. We've gathered tonight 'neath the rooftree of home,
A joyous and warmhearted band.
Our souls bud and bloom 'neath its bright, genial dome,
And peace gives a welcoming hand.
Alas! For the many who sorrow alone,
Where shivering want keeps the door,
With neither a bone nor a crust of their own.
Remember, remember the poor.

3. Oh! how the young chooks flush with rosy delight
As music and laughter go round,
And eyes sparkle bright as the stars of the night,
And hearts beat their merriest bound.
Alas! for the many who sorrow tonight:
The gentle, the loving, the true,
Whose hearts ne'er unite in the strains of delight
Whose voices a song never knew.
