Bruce Springsteen dedicated a song to "justice for Trayvon Martin" during a concert in Limerick, Ireland, on Tuesday.
The Boss said he was playing his track "American Skin (41 Shots)" as "a letter back home," following the controversial not guilty verdict in the prosecution of George Zimmerman over the weekend.
The song's lyrics, were written by Springsteen following the 1999 shooting of Amadou Diallo by four NYPD officers.
"Is it a gun, is it a knife
Is it a wallet, this is your life
It ain't no secret
It ain't no secret
No secret my friend
You can get killed just for living
In your American skin"
Stevie Wonder said at a concert in Quebec City, Canada, on Sunday that he would not perform in any state with a "stand your ground" law.
"I decided today that until the 'stand your ground' law is abolished in Florida, I will never perform there again," he said. "As a matter of fact, wherever I find that law exists, I will not perform in that state or in that part of the world."
"For those that we have lost in the battle for justice, wherever that fits in any part of the world — we can't bring them back," he continued. "[What] we can do is we can let our voices be heard. And we can vote in our various countries throughout the world for change and equality for everybody. That's what I know we can do."
