Choir! Choir! Choir! is a 200-person group from Toronto and they recently did a video asking Rick Astley to come sing with them. The rest is history and you can see it below.
I saw a video of @ChoirChoirChoir asking me to come perform Never Gonna Give You Up with them while I was in Toronto, so I took them up on the offer! Had a great time with these very talented people. Rick x https://t.co/WIztWcBl5W pic.twitter.com/99la6WRqOz— Rick Astley (@rickastley) April 18, 2018
