This would be 'We Are Safe' by Jim Woodland, which appeared on a 1980s LP called 'Ghosts'. Jim has written some excellent and hard-hitting songs, some of which are in the repertoire of partner Janet Russell. He used to be a Salami Brother but isn't seen too often on the folk scene these days, which is a pity for all of us.

I thought the song was about nuclear waste - or weapons.
