I'm seeking the lyrics to a wonderfully sentimental song performed by Glenn Yarbrough on his album Baby The Rain Must Fall. From what I remember, a couple of lines are as follows:

Walk on little boy
Your life has only started
A world full of joy
Is there for you to see
Walk on little boy
Our paths today have parted
So walk along, run along
But don't you wait for me.

I'm after this for a lonesome Dad whose son left home this past weekend... me!
