Legendary musician and future R&B Hall of Fame inductee Lester Chambers suffered injuries Saturday after he was attacked on stage for dedicating a song to Trayvon Martin.

According to police, the Civil-Rights-era leader of soul rock group The Chambers Brothers was performing at the Hayward-Russell City Blues Festival in downtown Hayward, California, when he was suddenly rushed by a woman identified as 43-year-old Dinalynn Andrews Potter after he dedicated Curtis Mayfield's People Get Ready to Trayvon Martin shortly following George Zimmerman's acquittal.

Chambers' wife Lola said the 73-year-old musician told audience members that Mayfield would have changed the lyric "there's a train a comin" to "there's a change a comin" were he alive today.
