I highly recommend the new Yo Lo Tengo EP Nuclear War. Mostly drums and vocals. One version has a children's chorus. It's a Sun Ra cover:

Nuclear war yea, yea, yea, they're talking about nuclear war / it's a Motherfuck-er, don't you know / if they push that button, your ass gotta go / and whatcha gonna do without your ass?"

Despair, hope and absurdity come together in a way that's easy to relate to these days.
