First showing (8)
I believe the answer is:
premiere
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">first showing</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for premiere that I've seen before include "significant performance" , "First public performance of a play or movie" , "First ever public performance" , "Mere pier (anag.)" , "Play's first public performance" .)
