On Jan. 16th something magical occurred at the Art Gallery of Ontario.

Over 500 people gathered to join Choir Choir Choir! to sing along to David Bowie’s 1969 track “Space Oddity.” The result was a hauntingly beautiful version of the song that’s sure to make at least a couple of your hairs stand on end. Watch it in the player above.

Choir! Choir! Choir! is a weekly drop-in, no commitment singing group that meets twice a week to sing arrangements of pop songs at Clinton’s Tavern in Toronto. Founded by Daveed Goldman and Nobu Adilman, Choir! Choir! Choir! does not hold auditions and welcomes everyone.
