An acoustic ballad released by the American rock band, Green Day, in 2005. It became a hit single in the U.S. and was also very popular in the U.K., Belgium and New Zealand. It became symbolic in the U.S. following Hurricane Katrina in 2005. Although the song has been tabbed by Lynne Garner for the Merlin, it is also playable on the strumstick since it does not go higher than the fourth fret.
