In case you are missing Jools Holland of a Friday night, you can catch him over on BBC4 tonight as he tells the story of his father-in-law, Rory McEwen, the aristocrat, artist, folk singer and pioneering TV presenter widely credited with introducing blues music to Britain. The Hootenanny star brings his relative's story to life with McEwen's paintings, archive material, and contributions from Van Morrison, David Dimbleby and Jonathan Miller.
