Stockard Channing has made a speedy -- some might say miraculous -- return to Broadway.

The 67-year-old Tony Award winner performed in "Other Desert Cities" on Friday night and plans to continue despite undergoing arthroscopic surgery on her right knee less than a week ago.

Channing felt her knee collapse backstage after the Nov. 18 show and missed seven performances. She performed in Saturday night's show and plans to be in today's matinee. An understudy performed Saturday's matinee and will do Wednesday's matinee.

The Jon Robin Baitz play, about a dysfunctional family wrestling with a deep secret, opened Nov. 3.

Sick George Michael cancels dates for year

George Michael's management said the singer has canceled all his remaining 2011 tour dates as he recovers from pneumonia.

A statement said the former Wham! frontman "is responding to treatment and slowly improving." The statement issued Friday said Michael "is ill with pneumonia and any other speculation regarding his illness is unfounded and untrue."

Michael, 48, was hospitalized in Vienna last week and canceled shows in Vienna, Strasbourg, France, and Cardiff, Wales.
