It was then re-recorded by Stone and his sister Julia, as the duo Angus & Julia Stone, and released on their 2010 album "Down the Way", as well as their 2010 EP "Big Jet Plane".
hypothesis: Big Jet Plane was not released for the first time in 2009.
reason: Big Jet Plane (although retitled) was released for the first time in 2009 - then rereleased with a duo in 2010.
