You should look for war poems and war songs. A google search of “war poems” will list lots of sites. Ideally we would have poems from many different wars. You may want to check with Ms. Hodge as well – the media center probably has a few For war songs, look for ones that somehow fit in with Booby Trap – “War Ensemble” by Slayer would not work.
You should create a doc for the poems you think we should consider.
If you have time, you could also start designing a poster for the show.
