If you were a successful BBC radio DJ with not one but two regular shows; if you assembled international tributes to Bob Dylan; if you worked as a musical director for film and you curated annual festival events like the Roaming Roots Revue then I'd have thought you might want a little rest from music on your days off.  This is certainly not true of Roddy Hart who, on top of all of the above, has been touring and making music of his own since 2007.
