WOMAN CHARGED WITH ASSAULTING SINGER AT BLUES FEST: HAYWARD (AP) — A woman has been charged with felony counts of assault and elder abuse in an attack on 73-year-old R&B singer Lester Chambers at a Northern California blues festival where he had just dedicated a song to Trayvon Martin. The San Francisco Chronicle reported Wednesday that Alameda County prosecutors charged 43-year-old Dinalynn Andrews-Potter of Barstow in the July 13 attack at the Hayward festival. Authorities say Chambers was performing the song "People Get Ready" for Florida teen Martin just after George Zimmerman was acquitted of second-degree murder when Andrews-Potter shouted something and shoved the singer into an amplifier.
