Yes, however we are talking about the lyrics for the song which could have been writen before this poem was published. We do know that the poem was published in 1977. We can also say that he was young man when he wrote this poem "all in my youth and prime". Also knowing that he lived from 1879-1940.

I know the poem that was published does say "For Ireland will be free". however, i think this backs up my original meaning of the words.
