Veteran soul singer Lester Chambers was admitted to a California hospital on Saturday (13Jul13) after he was attacked on stage for dedicating a song to slain Florida teen Trayvon Martin, shortly after the man accused of his murder was acquitted.
The Chambers Brothers star was performing at the Hayward Russell City Blues festival over the weekend when he decided to pay tribute to Martin with a cover of Curtis Mayfield and The Impressions' track People Get Ready.
However, a female member of the crowd appeared to take issue with the dedication and launched herself at the stage, knocking down the 73 year old in the process.
Chambers was briefly hospitalised to treat a "bruised rib muscle and nerve damage", according to his son Dylan.
The woman has since been identified by police as 43-year-old Dinalynn Andrews Potter and fans have rallied together to launch a Facebook.com campaign to charge the suspect with a hate crime.
A mission statement posted online reads: "Dinalynn Andrews Potter assaulted Lester Chambers on stage because he sang a song in tribute to Trayvon Martin, the victim of racist wannabe cop George Zimmerman and six white female jurors in Florida. Hate crime!"
Martin, 17, was shot dead in February, 2012, by neighbourhood watch volunteer George Zimmerman, who claimed he acted in self-defence.
He went on trial for murder and manslaughter charges last month (Jun13), but on Saturday (13Jul13), a jury found him not guilty on both counts.
Chambers wasn't the only star to comment on the ruling onstage - Beyonce held a minute of silence for Martin during her concert in Nashville, Tennessee on Saturday.
There's still no reunion planned though.
