In the event it reasonably appears to the Township Clerk, or any other official designated by the Township Committee for such purpose, that the number of persons gathered or gathering or waiting entry upon the licensed premises for any outdoor public entertainment licensed hereunder shall exceed 1,000 persons, the Clerk or other authorized official may give notice to the licensee immediately to withhold proceeding with the event licensed and shall then inform the Mayor or Township Committee promptly of this action. The licensee may thereupon request a hearing before the Township Committee forthwith, and the hearing shall be held as promptly as possible.
