We were waiting for the cellist at the North Entrance where we thought it was supposed to be but it turned out it was at the West Entrance.
Joseph Johnson, the Principal Cellist of the Toronto Symphony Orchestra played Tomaso Albinoni's Adagio. I think it was noisier than the north entrance because of the ventilation system but we were still able to hear him.
When he was about to get started the cello wasn't stable enough.
So he had to improvise.
But it still sounded beautiful!
