The Minutemen, a California band in the 1980s, are said to have been progenitors of alternative rock. They could be punky, but also like a jam band. The singer, D. Boon, died in a car crash in 1985.
Referencing body bags, this is somewhat of an anti-war song, or at least one critical of US foreign policy. Using the metaphor of a sports event, it appears to ask how long can citizens be cheerleaders – accomplices, really – to the violence. The band is hoping people will pull their heads out of the sand and raise their voices to, in democratic fashion, alter the direction of military policy.
