• Two days after giving birth to her first son, Wolfie, London born and Jersey reared singer-songwriter Nerina Pallot had the traumatic experience of seeing him taken to an intensive care ward following a health scare. Tormented by thoughts of how she'd carry on without him, she sought catharsis in music. Pallot told The Sun newspaper: "We went from the greatest day of our life to the worst. Wolfie came home and it was all fine but I kept thinking, 'What would happen if something went wrong?' I wasn't prepared for how much of a roller coasting parenthood would be - so I wrote 'If I Lost You' about it."
• The song features on Pallot's fourth studio album Year of the Wolf, which was mainly written during her pregnancy and is titled after her now healthy son.
• Pallot recorded this song quickly with both vocal and instrumentation laid down in one go.
