I think the two lines that were quoted occur in Brendan Behan's "Borstal Boy", and may be a variant of one of the songs about Treacy (tho' I don't think DB is actually mentioned by BB, but it's a long time since I read it). In addition to the two songs instanced by Philippa, there's one which Dominic Behan sang, which goes something like this. It's a bit raw, but then so's the Galtee Mountain-Boy.

"Fetch me a Parabellum and a couple-hundred shells;
Lead me to the 'Murder Gang' and we'll blow them all to Hell;
For just today I heard them say how Treacy met defeat,
How lovely Sean is dead and gone, shot down in Talbot Street.

[some verse here about how Treacy was surrounded, of which I can only recall the line about "his comrade with him slept"]

"They took the front, they took the back, they were all around the place;
Waiting for the word 'Attack', to set the house ablaze;
But how those English soldiers paled when out into the night
Sean sent a deadly stream of lead, challenging them to fight;

'Come on!' he cried, 'and show your hand; you've boasted for so long
How you could crush this lovely land with your army great and strong
Come, show this mettle which you say has made the whole World reel,
And ere there dawns another day, I'll show Tipperary steel'

He fought them off as best he could, outnumbered ten to one;
He spilt a bath of English blood before his race was run;
'No Surrender!' was his cry, and ever 'No Retreat'
Said Treacy brave, before he died, shot down in Talbot Street.



The Parabellum repeater seems to have been particularly favoured by the Volunteers of the time, judging by a number of photographs. The "Murder Gang" was based in Dublin Castle (and targetted, literally, by Collins). Evidently "No Surrender" should not be confined to Derry and/or the Rev I.P.
