Singer Oliver Tree said in a recent interview that he wouldn't leave his family "a f–king penny" if he died — while also predicting the world would appreciate his "stupid f–king songs" once he was gone. The quirky "Alien Boy" singer gave his harsh take while bizarrely dressed as Shrek — with a green face, neck and hands — on the April 24 episode of "The Zach Sang Show" in an interview going viral since his shocking death in a helicopter collision in Brazil on Sunday.
