Here's a link to http://www.peace-not-war.org/ a bunch of songs with sound files on the Peace Not War site. Some pretty powerful ones.
Here's one of them from Alabama 3:
WOODY GUTHRIE
As recorded by Alabama 3 on "Power in the Blood"
Another psychopath in Iowa loading up another round
while the NRA in Columbine hunt Marilyn Manson down
powder in the Pentagon cruel letters in the mail
some KKK white supremacist cooking up a dose of race hate
I don't need no country
I don't fly no flag
I cut no slack for the union jack
stars and stripes have got me jetlagged
Some baby in Afghanistan crying for its mama now
while the BNP scare refugees senseless up in Oldham town
hypocrites in Downing Street pouring petrol on the flame
Satpal cries, asks Paddy why do we always get the blame
I don't need no country
I don't fly no flag
I cut no slack for the union jack
stars and stripes have got me jetlagged
Sing a song for the asylum seeker
for the frightened baby on some foreign beach
you¹d better bang a gong and pray they reach
a safe harbour
Some mother in Jakarta lays down her weary head
in some free trade zone compound where they work you 'til you're dead
hunger stalks the corridor famine and disease
I seen the multinationals walking hand in hand with globalising marketeers
I don't need no country
I don't fly no flag
I cut no slack for the union jack
stars and stripes have got me jetlagged
