help me find this song.

I remember hearing a live U2 song (from a bootleg or something) all I
remember is Bono saying in the song:

What is this I see over here, I see a two letter word, I see S.F. and U2 is
that a girls name or does that stand for sharing ... ****words I can't
remember**** of Ireland, .. cause if it does I don't know how you can
****words I can't remember***** to it, because you bastards left them 51
wounded and **number forgetten*** dead, in the name of freedom, .....fuck
freedom

if I remember currectly it was the song Sunday Bloody Sunday (but where
from is it, and when) .
PLEASE HELP ME IF YOU CAN !!!!!!
