Lyrics and chords below; I worked the chords out from the Christy Moore version, which is easier to work out due to the standard tuning. There is a little riff between the G and Em where you play the A note on the G string within the G chord briefly before the chord shift. The chord is Asus2 I think.

  G
  I was an unmarried girl
  Em
  I'd just turned twenty-seven
            G
  When they sent me to the sisters
                  Em
  For the way men looked at me
  C
  Branded as a jezebel
  Em
  I knew I was not bound for Heaven
         C
  I'd be cast in shame
           D          Em
  Into the Magdalene laundries
  G 
  Most girls come here pregnant
  Em
  Some by their own fathers
  G
  Bridget got that belly
          Em
  By her parish priest
  C
  We're trying to get things white as snow
  Em
  All of us woe-begotten-daughters
          C
  In the streaming stains
         D          Em
  Of the Magdalene laundries
  C
  Prostitutes and destitutes
       Em
  And temptresses like me--
  C
  Fallen women--
                  Em
  Sentenced into dreamless drudgery ...
  C
  Why do they call this heartless place
  Em
  Our Lady of Charity?
     C       Em
  Oh charity!
  G
  These bloodless brides of Jesus
   Em                    
  If they had just once glimpsed their groom
  G
  Then they'd know, and they'd drop the stones
  Em
  Concealed behind their rosaries
  C
  They wilt the grass they walk upon
  Em
  They leech the light out of a room
                 C                  D
  They'd like to drive us down the drain
                    Em
  At the Magdalene laundries
  G
  Peg O'Connell died today
            Em
  She was a cheeky girl
  A flirt
  They just stuffed her in a hole!
  G                                        Em
  Surely to God you'd think at least some bells should ring!
  C
  One day I'm going to die here too
              Em
  And they'll plant me in the dirt
       C
  Like some lame bulb
                             Em
  That never blooms come any spring
           C
  Not any spring
              Em
  No, not any spring
           C       Em
  Not any spring

Hope this helps. My wife plays this on tenor guitar and sings it. Really good song.
