According to Billboard.biz, a music publishing company, Larrikin Music, is suing over the song "Down Under," claiming the "flute riff" in the song was lifted from the "refrain of a 1934 children's tune, 'Kookaburra Sits in the Old Gum Tree.'"

The band's record labels are asking that the case be tossed out. And according to the Billboard report, "They also question whether Larrikin even holds the copyright to that song -- a Girl Guide campfire favorite from New Zealand to Canada -- and therefore whether it has the right to sue." - more on this story
