More than 1 line really, but i think back to the 1984 song from Band Aid, when Bob Geldof and Midge Ure decided it was time to raise awareness and money to help with the famine in Ethiopa, releasing "Do they know its Christmas?". The hope was for it to raise £70,000 for the campaign that year. It actually went on to make £8 million.

The lines i'm focusing on in partucular are:

"There's a world outside your window
And it's a world of dread and fear

Where the only water flowing

Is the bitter sting of tears

And the Christmas bells that ring
There are the clanging chimes of doom"

Words that stand the test of time I think.
