Two days before the 9/11 terrorist attacks, Ross performed "God Bless America" at the U.S. Open tennis championships before the tournament's women's final, between Venus and Serena Williams. Immediately following the attacks, Ross performed the song again at Shea Stadium, before the Mets first game, after driving cross-country to be with her children (in the wake of the attacks, flying in the U.S. was temporarily restricted.). Ross teamed with legendary singers Patti LaBelle, Eartha Kitt among others for a Nile Rodgers-produced recording of Sister Sledge's classic disco hit, "We Are Family", recorded to benefit the families of 9/11 victims.
