Here's the Mackay poem:The Good Time Coming. Foster has made virtually no changes to the poem in setting it:

He inserted the repeated A good time coming 3rd line
The contractions giv'n and ev'ry are in full in the poem
The poem has Hateful rivalries rather than Shameful rivalries
The poem has Till limbs and minds rather than Till limbs and mind



The poem was from Voices From The Crowd, 1845-46 and the collected edition I linked to above, quotes the preface to the 5th edition of 1857:

"The Poems entitled "Voices from the Crowd" were for the most part written in the year 1845 and in the early part of 1846, a time of social and political agitation. The Corn Laws were unrepealed; and Sir Robert Peel had not announced the downfall of the old protective system. Many of them were intended to aid - as far as verses could aid - the efforts of the zealous and able men who were endeavouring to create a public opinion in favour of untaxed food, and of Free Trade and free intercourse among all the nations of the world. They were written as plainly as possible, that they might express the general sentiment of the toiling classes in phraseology broad, simple and intelligible."
