There have been a lot of songs written about space, but how many songs have actually been written in space?

Watch this video as astronaut Chris Hadfield, from aboard the International Space Station, performs “I.S.S. (Is Somebody Singing)” with Ed Robertson, the rest of the Barenaked Ladies and the Wexford Gleeks from Wexford Collegiate School for the Arts, who were all at the CBC studios in Toronto.

The song, which was written by Hadfield and Robertson in partnership with Music Monday, CBC Music and the Canadian Space Agency, explores what it’s like to look down on the Earth from outer space. It will also be the official song for the 2013 edition of Music Monday, which takes place on May 6.

David Bowie may have paid tribute to the great unknown with songs like “Starman” and “Space Oddity,” and Rush, a favourite of Hadfield’s, penned an entire space-rock opera, 2112, but how will they compare to a song written in space, by an actual astronaut?
