Muse vocalist Matt Bellamy wrote this song about his baby son, Bingham, after his fiancée, actress Kate Hudson, gave birth to the child on July 9, 2012. The ode to fatherhood kicks off with a sample of Bingham's heartbeat, which Bellamy recorded on an iPhone just before he was born. Bellamy explained to The Sun: "A couple of days before Kate gave birth we went for a check-up and I recorded it on my iPhone as I thought it was an amazing sound. I found it three months later and plugged it in to the recording system, recorded a tempo and the orchestral piece around it. Then I wrote the lyrics about wanting to lead and protect, all the feelings that having a kid evokes."
