McAdams treated the audience to a Girl Scout song she said Keaton used to sing on movie sets:

Then, after an In Memoriam video package, Barbra Streisand spoke at length about Robert Redford, who died Sept. 16 at 89.

Streisand praised Redford’s advocacy for freedom of the press, fostering rising artistic voices at his Sundance Institute in Utah and protecting the natural environment.

“I called him an intellectual cowboy who blazed his own trail and won the Academy Award for best director,” Streisand said. “Bob had real backbone on and off the screen.”
