Beyoncé premiered her version of "God Bless The USA" on CNN's Piers Morgan Tonight this evening (May 5.) The song is available exclusively through iTunes and proceeds will be donated to the New York Police, Fire Widows' and Children's Benefit Fund. In a statement, Bey said, "We were all affected by the tragedies of 911 and continue to keep the families who lost loved ones close to our hearts. Lee Greenwood, the writer of the song, is also donating his proceeds to help the 911 families." Previously, her partner in crime and husband Jay-Z donated all proceeds from his "Answer the Call" concert at Madison Square Garden to the fund as well.
