The 73-year-old lead singer of the 1960s soul rock group The Chambers Brothers was performing at the Hayward Russell City Blues Festival in Hayward, California on Saturday when the incident happened. Chambers was singing the civil rights-era song People Get Ready by The Impressions in honor of Martin when a woman identified as 43-year-old Dinalynn Andrews Potter climbed up on stage and knocked the singer over. According to a fellow musician Kurt Crowbar Kangas in a comment on Facebook, Potter yelled "it's all your fault," right before she pushed Chambers, who "went down hard."

The woman was subdued by police and Chambers was taken to the hospital. He sustained an 8-inch scratch on his back, bruised ribs and nerve damage.
Trayvon Martin, 17, was fatally shot after George Zimmerman, a neighborhood watch coordinator, confronted him for looking suspicious. Zimmerman claimed that he shot Martin in self-defense, and was found not guilty of murder on July 13. The verdict sparked a nationwide debate centering around race relations.
