Beyoncé debuts charity single God Bless the USA

Beyoncé is releasing her second new single in as many weeks, following Run the World (Girls) with new charity track God Bless the USA. She unveils patriotic power-ballad on Piers Morgan Tonight, with proceeds going to families of 9/11 victims.

God Bless the USA was written and originally released in 1984 by country musician Lee Greenwood, and was played at this year's Republican party convention. Its popularity increased after 9/11, and it was re-released following the 2003 invasion of Iraq. Beyoncé's version will raise funds for the New York Police and Fire Widows' and Children's Benefit. The singer originally recorded the track in 2008 for the Obama presidential campaign, but never released it. It seems likely the death of Osama bin Laden on Monday has been the spur for this release.
