During a performance of Handel's Laudate Pueri Dominum in the Musica Viva series' 60th-anniversary concert, Allen, who had been ill with the flu, fell to the stage and was lying on the podium.
According to Peter McCallum, the Herald's reviewer, "It was quite dramatic. She was white as snow."
The doctor who rushed to the stage to attend her was Bashir, who is a psychiatrist. The choir finished the movement, and Allen was carried offstage. The governor went backstage as well.
The governor's office would not comment on what happened at the concert. "Anything Professor Bashir does she does without drawing attention to it," a spokesman said.
The performance continued with soprano Josie Ryan singing Allen's solo part, and a duet with soprano Emma Kirkby.
Allen was discharged from the hospital, and has been ordered to rest for three days. She plans to be recovered in time to perform in the same program on August 24.
