The missing bits:

second half of 2nd verse:

The rich may steal the power, but the glory's ours alone,
When we go rolling home, when we go rolling home. Chorus

The frost is on the hedgerow, the icy winds do blow,
While we poor weary labourers strive through the driving snow
Their dreams fly up to glory, up where the lark has flown
When we go rolling home, when we go rolling home. Chorus

The summer of resentment, the winter of despair,
The journey to contentment is set with trap and snare
Stand to and stand together, your labour's yours alone
When you go rolling home, when you go rolling home. Chorus

You've got the last verse from Dai.

I could regret this but I'm going to rise to the bait and ask why girls shouldn't sing this song?^^
