Aye Martin, you're right - it's based on Crawford Howard's version - I'd forgotten that. The one in the DT is slightly different from the one Fintan Vallely recorded on the Scitheredee album, and is missing a final verse:

And you, Eric Bogle, just what was your game?
Do white crosses mark out the road to your fame?
Did you not think the Fureys would drive us insane?
Could you not call them off; Jesus, we're not to blame!
And what's all this talk about shellfire and smoke?
Sure with PA and cigarettes the pubs are no joke
Where we drink to his memory each weekend til we're broke
Making Willie McBride's fans consumptive auld soaks

and a chorus:

Did he sing the song badly?
Did we gulp our pints madly?
Did we fall asleep before we finished our round?
Did the barstaff cry "last drink" to stir us?
And did the punters cry "thank god it's over"?
