The co-founder of the 1960s band TheChambers Brothers said he was singing about love and peace, as a tributeto Martin. He had just told the audience why he chose Mayfield's"People Get Ready."

"(Mayfield) sang 'People get ready,there's a train a coming.' And if he was here today singing it, he wouldprefer probably that we would say, 'People get ready there's a change acoming,'" Lester Chambers told KPIX 5.

Officers said 43-year-old suspect Dinalynn Andrews-Potter of Barstow refused to speak to police. She was cited and released.

LesterChambers has a new album coming out this week, but because of theattack he is too afraid to do live performances to promote it.

Hewas not afraid to offer the suspect forgiveness. "I would say to her,get a little God in your heart, and let a little love come out of yoursoul."

The Chambers family believes the suspect should be charged with a hate crime, because the song was dedicated to Martin.
