Came to mind:

Portraits hung in empty halls
framless heads on nameless walls
with eyes that watch the world and can't forget
like the strangers that you've met

The ragged men in ragged clothes
a silver thorn
a bloody rose
lie crushed and broken on the virgin snow
now I think I know
what you tried to say to me
and how you suffered for your sanity
and how you tried to set them free
they would now listen
they're not listening still

Perhaps they never will
