Kele told The NME June 12, 2010: "All the songs (on The Boxer) are about being lost and then being found. All the songs are about a period of darkness and then a period of positivity and light. 'All The Things I Could Never Say' is about stepping away from a lover when the love isn't there any more."
David Bowie's "Space Oddity" tells the story of an astronaut who cuts off communication and floats into space. The BBC used it extensively in their coverage of the 1969 moon landing - an odd choice considering the lyrics.
