On the first "Tullimentan" of this season: we look at artistic responses to the story of Dr John Rae, including: a conversation with ex Python and national treasure Michael Palin about his new book "Erebus"; a look round the exhibition "The North West Passage" at the Pier Arts centre with internationally renowed artist Barbara Rae; and hear from Aimee Leonard how she devised a new song to honour the Orphir born explorer. We'll also mark what would have been film maker and poet Margaret Tait's one hundredth birthday. And investigate what happens to your brain when you play a musical instrument.
