This song was inspired by the love affair between writer Ann Druyan and her late husband, the cosmologist Carl Sagan.
Sagan was chosen to chair a committee that selected a collection of songs, sounds and images representing planet Earth that were put on a pair of golden discs
sent into interstellar space on board the two Voyager spacecraft launched in 1977.
Ann Druyan was on the committee as creative director, and she and Sagan fell in love when they were compiling the records. Druyan had arranged to record her own heartbeat and put it on the Golden Record. The day before she planned to do this, Sagan asked her to marry him, resulting in a recording of a young woman madly in love now floating out there in the cosmos. The Avalanches' Robbie Chater told NME
: "We just thought that was the most beautiful idea."
