"Sometimes Love Is Letting Go" is Chapter 13 of Suzi Quatro's autobiography, Unzipped
. The song, which was co-written with Shirlie Roden, was inspired by a conversation with her late mother who in response to asking her why she had allowed her to go on the road so young replied: "Because, Susan, sometimes love is letting go!" Quatro said: "That was one of the most poignant things my mother
had ever said to me." The book is in fact dedicated to her mother: "The only person in the world who knew me inside and out!"
