I have another song here with the same title ( if the song posted by Sue is not the one you're looking for ). It starts like this...
Sons of the sea, sons of the saint
Who is the child with no complaint
Sons of the great sons unknown
All were children like your own...
This one was written by Eric Blau & Mort Shuman with music by Girard Jouannest and recorded by Judy Collins. If this is the song you were looking for, e-mail me at the address below and I will type out the whole song ( it's kinda long ) and e-mail it back to you.
