VISIONARY (Johnny Nash, R.I.P.)

You can get the facts about the soul singer, discoverer of teen pop, producer of Bob Marley, reggae pioneer, on Wikipedia. Then again, there’s the truth:
 
Thou shalt remain, in midst of other woe
Than ours, a friend to man, to whom thou say’st,
         “Beauty is truth, truth beauty,—that is all
                Ye know on earth, and all ye need to know.”
John Keats
