Prince debuts song about Baltimore at 'Rally 4 Peace'

BALTIMORE (AP) — Prince took the stage in Baltimore before thousands of fans who were dressed in gray in tribute to a man whose death in police custody prompted riots and drew international attention.

The pop star announced Sunday's "Rally 4 Peace" concert at the Royal Farms Arena Baltimore after weeks of protests sparked by Freddie Gray's death. During the show, Prince debuted a song he wrote for the city after Gray's death.

"For those who have lost loved ones, we're here for you tonight," Prince told the crowd before launching a set that included his most famous hits.

Prince also called on the city's youth to fix a "broken system."

"We're tired of crying and people are dying, let's take all the guns away," the song refrain says.

"If there ain't no justice then there ain't no peace."

Baltimore State's Attorney Marilyn Mosby, who charged six officers in Gray's death, was invited to the stage and waved to the crowd.
