<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">put on a performance</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for staged that I've seen before include "Presented a play" , "Put on play or other performance" , "Orchestrated" , "Mounted (a play)" , "Get ads (anag) - performed" .)
