Unfortunately, the DT lyrics have multiple errors, if one takes the words sung by the author, Dominic Behan, on the Rebellion LP. The order of the verses also differs, as indeed does the title of the song. On the album it is titled 'Parnell'.
The original words as sung by the author are below with the erroneous wording in brackets. The order of verses has also been corrected.

Oh have you been to Avondale
And (wandered) lingered in (the) her lovely vale
(Where) While tall trees whisper(all)low the tale
Of Avondale's proud eagle

Long years that green and lovely (vale) glade
(Has) Had nursed Parnell, (our) her grandest Gael
And cursed the land that (has) had betrayed
(Fair) Bright Avondale's proud eagle

Where (fame) pride and ancient glory (fate) fade
Such was the land where he was laid
Like Christ was thirty pieces paid
For Avondale's proud eagle
