I'll sing you a song and it won't take long;
All coppers are con-stables
I'll sing you another as good as the other;
All coppers are con-stables.


The break in the second and fourth lines was always exaggerated, and it should be noted that the 'o' in constables is pronounced as some people pronounce the 'o' in Monmouth or Coventry

Cheers
