Knight co-wrote this song with Jimmy Hogarth (Adele, Duffy). It appears on her sixth album, 100%.
Knight explained on her website: "This is a song I wrote from the sad memory of a previous relationship. Sometimes as a relationship reaches its end, you can become strangers, not even speaking. As though made of stone. Although it has a sad lyric, the feel of the track is very upbeat, especially when it hits the chorus! There is a recurring guitar signature throughout which is very sing-a-long, in fact I join in with it at the final chorus."
