Cass Dillon (May 3, 1986) is a singer-songwriter from Long Island, New York, whose first release is a song written by Billy Joel titled "Christmas in Fallujah".
Dillon's first major release was written by Billy Joel and titled "Christmas in Fallujah". Joel wrote the song after receiving many letters from military service members serving in Iraq but chose not to perform it because he "thought it should be somebody young, about a soldier's age." Dillon came to Joel's attention through his longtime musical director Tommy Byrnes and artist manager Stefano DiBenedetto with whom Dillon had been working. The song was released to the public on iTunes on December 4, 2007, the day after being previewed on The Howard Stern Show. Net proceeds from the song will be donated to Homes For Our Troops, which builds homes for severely wounded veterans of Iraq and Afghanistan.
