Hey, man, we did make a difference!
Think about the songs we used to sing in the early/mid 60s-
"If you miss me at the back of the bus"
"Carry it on"
"There but for fortune"
"The crow on the cradle"
"If I had a hammer"
"One man's hands"
"Turn, turn, turn"
"We shall overcome"

There was a lot of unfair stuff going on then. OK, there's still unfair stuff but it's changed, hasn't it? People seem to be more materialistic these days.

I guess there will always be greed and despots in this world but I'd like to think life is better nowadays for Afro-Americans, for Vietnamese, for all sorts of minority groups.
The world has changed and no doubt it will continue to change, hopefully in a way that is best for the greatest number.

I've just noticed - a lot of those songs came from Pete Seeger records!!! I love Pete Seeger! (And I have done since about 1952.)

There are probably just as many people today writing songs and singing about current world issues. Let's see if they can change the world! I reckon we did!
