what make this such a rocker

the choppy rhythm, splitting the difference between Steppenwolf "Magic Carpet Ride" and Sly & Family Stone "Thankyafalletinmebemiceselfagin" (or howevayaspellit)

and the tone of the lead guitar

as for the obnoxious lyric, supposedly it's some kind of allegory to do with the Vietnam War, or so I read somewhere
