Document 3: Billy Joel: On December 1, 2007, Joel premiered his new song "Christmas in Fallujah". The song was performed by Cass Dillon, a new Long Island based musician, as Joel felt it should be sung by someone in a soldier's age range (though he himself has played the song occasionally in concert.) The track was dedicated to servicemen based in Iraq. Joel wrote it in September 2007 after reading numerous letters sent to him from American soldiers in Iraq. "Christmas in Fallujah" is only the second pop/rock song released by Joel since 1993's River of Dreams. Proceeds from the song benefited the Homes For Our Troops foundation.
