<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">john or paul</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for bunyan that I've seen before include "author John" , "The Pilgrim's Progress author, d. 1688" , "Writer" , "Paul -, US mythic hero" , "John . . . . . . wrote 'The Pilgrim's Progress'" .)
