it's a very simple song, sung by Brighton singer John O'Reilly who is known all 
over south England and Ireland.

  Am     Em7
Forefathers fought

  Dmaj7  C#
Oh yessir they did

  Ab     Am
You may ask how?
  
  F#m7
But rue the day!


chorus:

 A
Everyone knows us

 C#m
Haters among'em

 Em
Get them and their children

 G               F#m
Them fuckers deserve it!
