TORONTO — Tragically Hip frontman Gord Downie made a surprise appearance Thursday night at Toronto's Massey Hall with Blue Rodeo and the Sadies.

In a video clip circulating on social media, Downie is seen joining the bands onstage for a rendition of Blue Rodeo's "Lost Together.''

A smiling Downie held a piece of paper as he stood by one of the microphones to contribute backing vocals.

Downie has a history of collaborating with the Sadies and recorded the 2014 album "And the Conquering Sun'' with the band.

Downie revealed in May that he has glioblastoma, an incurable and rare form of brain cancer.

The father of four, whose 53rd birthday is Monday, has most recently been promoting his "Secret Path'' solo multimedia project, which recounts the life of 12-year-old Chanie Wenjack, who died in 1966 after running away from a residential school.
