Rankin's song, 'The Sixth Stone', appeared on a compilation album that brought together some of Scotland's top writers and musicians. In an interview with the Scotsman, Ian Rankin recalls: "The song's all about Stu's move from Pittenweem to the Route 66. I'm quite interested in people who are on the edge of history - onlookers in big events.
All the way through the sixties he was there in the background but he was always more interested in the golf course than the groupies, drink and drugs. I was fascinated by him as a character, and since you're writing a lyric, why not write about someone involved in the music industry? ". One can find the song's full lyrics in the afore-mentioned Scotsman article.
