[Fiji Hill]

In the 1960's, Roger Dewey recorded a Vietnam War version of the tune, which incorporates elements of John Brown's Body :

The bodies of the commies are a-moldering in the dew;
We shall frighten big Red China till she trembles through and through;
They call us the aggressor, but themselves the aggressor crew;
As we go marching on.

[Killborn]

That is most good. :)
