The Molly Maguires as performed by the Dubliners

   F                C
   Make way for the Molly Maguires,
            Bb                                         F
   they're drinkers, they're liars, but they're man.
   F                C
   Make way for the Molly Maguires,
           Bb             C             F
   you'll never see the likes of them again.

Dm                  F                                        Dm
Down the mines no sunlight shines, those pits they're black as hell;
      F             Bb                   F       C    F
in modest style they do their time, it's Paddy's prison cell;
         Dm                  Am               Bb                      C
and they curse the day they travelled far and down their tears with a jar.

   Make way for the Molly Maguires...

Backs will break and muscles ache
down there no time to dream
of fields afar of a womans arm
just dig that bloody seam
though they drain their bodies and their brow
who dare to push them around.

   Make way for the Molly Maguires...
