I receive Ian Rankin's newsletters, and in the most recent one it said:
Well, Standing In Another Man’s Grave is finally out in paperback here in the UK. As some of you will know, it takes its title from a mondegreen, meaning a misheard song lyric. For some time, I’d thought my friend the musician Jackie Leven had been singing about ‘standing in another man’s grave’ – it was only when I saw the lyrics that I realised it was rain he was standing in. But by then it was too late – I had my title.
