As a part of their Music Monday celebrations, choir students from Ecole Poirier elementary school took to the streets and sang their songs around town. They stopped at Shoppers Drug Mart and serenaded the staff and customers with the I.S.S. (Is Somebody Singing), the song Hadfield co-wrote with musician Ed Robertson of the Barenaked Ladies. They followed that with their school song, and then ventured out onto the front lawns to pose for a photograph. Earlier that day, Poirier students sang via live broadcast with hundreds of other schools across Canada. Canadian astronaut Chris Hadfield used his last video stream from the to lead this sing-along. Just after the sing-along, Hadfield (@Cmdr_Hadfield) sent a tweet from Twitter, saying, "That was FUN! Thanks everyone for being a part of Music Monday. Sharing joyousness and art is a vital part of life, great to share from here."
