Join John Kelly for his weekly Sunday Service, where a special guest joins him on the Mystery Train and picks the tunes.

This week, John is joined by acclaimed playwright Enda Walsh, who discusses his collaboration with David Bowie on the musical Lazarus and spins an eclectic mix ranging from The Smiths to Horslips to Sampha and - naturally - the late great Thin White Duke.
