you think you can tell?

SO, SO YOU THINK YOU CAN TELL
HEAVEN FROM HELL
BLUE SKIES FROM PAIN
CAN YOU TELL A GREEN FIELD
FROM A COLD STEEL RAIL?.
A SMILE FROM A VEIL?
DO YOU THINK YOU CAN TELL?
AND DID THEY GET TOU TO TRADE
YOUR HEROS FOR GHOSTS?
HOT ASHES FOR TREES?
HOT AIR FOR A COOL BREEZE?
COLD COMFORT FOR CHANGE?
