The first half was tepid and eminently forgotten, though Aldershot surprised Notts with their strength and mobility up front and they probably felt they should have been ahead at the break.
However, six minutes into the second period, the Shots got the goal they had long threatened.
It came from only their second corner of the match to that point and was headed in by central defender Anthony Charles off the underside of the bar.
Notts County were behind for only three minutes when - also from a set play - they fashioned a leveller.
It was an exact replica of a goal scored at Exeter the previous week with the same two players involved.
Matt Hamshaw delivered a free-kick so accurately that defender and club captain Michael Johnson was able to steer it home at the back post with the deftest of touches.
Either side could have won it after that and Notts County had a scare when a close-range effort from Louis Soares nearly squirmed away from the clutches of goalkeeper Russell Hoult.
County have made a habit in recent matches of scoring injury-time goals and so it proved again.
In the fourth of five added minutes Richard Butcher rose to a lovely left-wing cross from Jamie Clapham to find the roof of the net for his fourth goal of the season in all competitions.
It sent the biggest Meadow Lane crowd of the season deliriously happy, largely because it fittingly honoured Sirrel's memory so perfectly.
