It was one of the biggest pop hits of the 1980s — a song that people loved to dance to, loved to hate and couldn't get out of their heads.

And last week British pop legend Rick Astley performed an unforgettable rendition of "Never Gonna Give You Up" with 200 singers from Choir! Choir! Choir! — an open group founded by Toronto's Daveed Goldman and Nobu Adilman that allows anyone to join in and sing.

"Hey Rick Astley, we want you to come and sing with us. We will sing with you," pleads Goldman at the start of a video, below. "We love your music, we celebrate music, and you have some wicked songs, man. So come and sing with us."

Astley took the group up on the challenge, then joined them for "a sing-song," and the result is amazing. Watch:

At the end of the video, Astley — who also appeared on q — challenges Dave Grohl and his band the Foo Fighters to join the choir next.

Later on Twitter, the Foo Fighters seemed to accept the challenge.

HELL YA!! See you in Toronto July 11th?!! —@choirchoirchoir

First formed in 2011, Choir! Choir! Choir! began as a one-off event at a birthday party for Canadian musician Matt Murphy, but soon grew to become one of Toronto's most beloved groups.

They have received huge online audiences for their tributes to beloved musicians from David Bowie to Gord Downie; they performed a vigil for the victims of the Orlando nightclub shooting and raised funds for Syrian refugees; and they have opened for performers from Patti Smith to Jay Leno to Tegan and Sara.

Last November, they also performed the Canadian anthem before the 2017 Grey Cup in Ottawa.

"Never Gonna Give You Up" was a number one hit worldwide in 1987, eventually topping the charts in 25 countries, including the U.S. and Canada. The song also won best British single at the 1988 Brit Awards.

After his massive success, Rick Astley officially retired from the music business in 1993 at the age of 27, but returned 10 years later and has since released several albums and compilations — and won internet fame when he became the subject of an Internet meme called rickrolling.

Astley's most recent album was 2016's 50, which was released shortly after the singer turned 50.
