I have never been an anti-war protester but the words of many songs in the 60's are quite chilling and make you think.
Listen to this rendition of Sky Pilot done in 2006. Eric can still sing.
Pay attention at 4:50 and the change of lyrics
The Original Lyrics read
You'll never, never, never reach the sky
You're soldiers of God you must understand
The fate of your country is in your young hands
May God give you strength
Do your job real well
If it all was worth it
Only time it will tell
