“16/04/16 (Jack’s Song)” is a song written by Robbie about his friend Jack Graham who died of leukemia on April 16, 2016.

He sings about Jack and some of the special memories he has of the times they spent together.

In an interview, Robin speaks on his former friendship with Jack:

Jack was my first best friend. He was my next door neighbour up until the age of 8, and us and his brother and sister used to play pretty much every day. We even built a bridge out of tree stumps which we used to climb over the fence between our gardens.
