This past February, Canadian astronaut Chris Hadfield and Barenaked Ladies' Ed Robertson co-wrote "(I.S.S.) Is Somebody Singing?" for Music Monday 2013

Then, in an unprecedented cross-hemisphere collaboration, the song was recorded live by Barenaked Ladies and the Wexford Gleeks choir in the Toronto CBC Studios along with Hadfield aboard the International Space Station, which you can watch above.

The next step takes place on Music Monday, May 6, as thousands of schoolchildren will perform "(I.S.S.) Is Somebody Singing?" simultaneously across the country at exactly 12 p.m. ET.

Update 

Now, CBC wants to give choirs nationwide the chance to be part of a special performance to be broadcast across the country! We’re looking for one amateur Canadian choir to make up part of a show coming later this summer. Details will be announced May 29.

If your choir has what it takes to be enjoyed all across the country, tell us why. Send your story, details and a link to where we can watch one of your performances to issomebodysinging@cbc.ca.

One select choir will be featured, so this is your opportunity to show the nation what you’ve got and to be part of an exciting TV broadcast.

Filming will take place mid June 2013.
