Gargoyle, there is a midi link in the DT under "Follow the Band", which is a non-military version, but it doesn't work. Oscar Brand may have recorded this as well, but I remember singing it in a club in Da Nang. Other verses I remember are (in abbreviated version):

...A sergeant....kicks butt

...A looie...screws up

...A captain...licks ass

...A major...makes plans

...A colonel...dicks off

...A warrent...does everything

I suspect that this particular version was put together by the WOPAs (Warrent Officer Protective Association), an officially non-existant organization with about as much clout in the Army as the WPPA (West Point Protective Association).
