David Bowie fans in Toronto paid tribute to the Starman this weekend with a one-of-a-kind performance of his legendary cosmic opus Space Oddity

More than 500 people gathered in the grand atrium of the Art Gallery of Ontario to belt out the classic song with the founders of Choir! Choir! Choir!, a group that brings pop music aficionados together each week in cool places to sing unique arrangements of hit songs.

The result was a pretty epic salute to the U.K.-born musician, who left an indelible mark on the lives of people around the world. 

Bowie died last week after an 18-month fight with cancer.
