St Mary’s Cathedral Lights of Christmas

We have been invited to take part in the annual performance at St Mary’s Cathedral with three other Sing Australia Groups (Ashbury, Gordon and Sutherland).
We will be singing on a stage, and all care will be taken when entering and exiting the stage by stairs, holding on firmly to the handrails.
I see no perceived risks to our singers so long as they exercise caution on the stairs. We sing for about 40 minutes.
Public transport is recommended to travel to the event, or there are parking stations nearby.
