I read that Canadian astronaut Chris Hadfield is the first Canadian ever to perform a spacewalk on his trip to deliver Canadarm2, (the next-generation robotic arm), to the International Space Station - I was pleased to see he is taking (has taken?) Joni Mitchell CDs in his 'travel kit'. My guess - Blue for 'This Flight Tonight' "Up there's a heaven, down there's a town Blackness everywhere and little lights shine" or Hejira for "Refuge of the Roads" (to remind him to take a photograph of the earth on his way back) PaulC
