Concert receipts (4)
I believe the answer is:
gate
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">concert receipts</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 gate that I've seen before include "Plane-boarding point" , "Frame for closing an entrance" , "Confine to college" , "Punish student" , "Five-bar opening?" .)
