SLight correction on the first line of Verse 1.

I am almost certain it should read
"Sé do bheatha a Bhanba léanmhar"
Banba is an old poetic name for Ireland.

I'm intrigued that the line about gan bheith bheó ach seachtain. Only living for a week afterwards. I had always thought this was a reference to the fact that the 1916 rebellion of which Pearse was one of the leaders lasted exacly a week. It now looks as if this line was part of the Jacobite song on which Pearse based his song. Prophetic or what?
