The first lines of the first song I ever sang to my then-infant son were Bob Dylan's:
 
"Come mothers and fathers
from throughout the land.
And don't criticize what you can't understand.
Your sons and your daughters are beyond your command.
And your old road is rapidly agin'.
So please get out of the new one if you can't lend your hand,
For the times they are a-changin'."
 
That was twelve years ago. Since then, I've found the words to be truer and truer each year - not only in terms of my twelve-year-old but also in terms of my kids in Philadelphia.
 
Thanks.
