The song originally had different lyrics. It was written as an anti-vietnam song, but there were allready a lot of anti-vietnam songs at the time, and they didn't want to make an obvious political statement. So they thought they'd do something else with the song, something more original, with more humor.
So they transformed it into this romantic love song, which turns out to be a travestite.
The contrast between this sweet love song and the dark "I love the dead" was meant as an extra humurous effect.
