The 39-year-old first time father said 'Go Gentle' was inspired by one-year-old Theodora Rose, affectionately known as Teddy, reported Contactmusic.
"(The track is about being) worried she might meet someone like me - and what she should do if she does. My daughter inspires my life greatly. There used to be a huge hole in my life that I wrote many albums about.
"I didn't realise it was a wife and daughter shaped hole, they've plugged that gap. Everything I do, I do for them now. When daddy goes to work it's daddy going to work, not Rob going to work. I feel like there's a purpose to everything.
