This unabashed, jaunty declaration of love finds Blunt sending postcards from his heart to his lover. It is one of many songs on Moon Landing that concern matters of the heart and the record's release coincided with Blunt's relationship with Sofia Wellesley, the granddaughter of the current Duke of Wellington and a descendant of the Iron Duke himself. During an interview with the Daily Telegraph, Blunt was asked if the album is about Sofia? "I think I probably tap into lots of different things along the way," he replied. "One song might come from a mixture of different experiences. But, yes, this album is absolutely about my life where I am at the moment, rather than my life in the past."
Blunt originally wrote this ukulele-led song on the piano.
In The Beatles "When I'm 64," Paul McCartney asks a woman if she'll still be there for him when he's 64. In 2006, he got his answer when shortly before his 64th birthday, he and Heather Mills separated.
