International Space Station Commander Chris Hadfield led a high-tech concert Monday, joining thousands of young voices from around the world — with his own voice from space.

Students, musicians and other participants across Canada and as far away as Singapore and Australia sang along with Hadfield, belting out ISS — Is Somebody Singing?, the song Hadfield co-wrote with Ed Robertson of the Barenaked Ladies, to celebrate the ninth edition Music Monday, an annual celebration put on by the Coalition for Music Education.

This year, the event was a partnership with CBC Music and the Canadian Space Agency.

The concert is Hadfield's final live link from the space station before he returns to Earth on May 13.

ISS — Is Somebody Singing? was commissioned by and the Coalition for Music Education.

The Coalition for Music Education is a non-profit organization that promotes the benefits of music education for young people. The group says it created Music Monday to "celebrate the galvanizing power of music and demonstrate how that power is rooted in school music programs."
