Gord, 52, who formed the legendary Canadian band with guitarist Rob Baker, 54, in 1984, learned of his diagnosis in December last year (15).

In a statement posted on Facebook signed by Gord, Rob, bandmates Johnny Fay and Paul Langlois, the group revealed the singer's battle with brain cancer.

"A few months ago, in December, Gord Downie was diagnosed with terminal brain cancer," the statement read. "Since then, obviously, he’s endured a lot of difficult times, and he has been fighting hard. In privacy along with his family, and through all of this, we've been standing by him."

In the touching and defiant message, the band revealed they would attempt to play one final tour before the musician passed away.

"After 30-some years together as The Tragically Hip, thousands of shows, and hundreds of tours...We’ve decided to do another one," the statement continued.

"This feels like the right thing to do now, for Gord, and for all of us. What we in The (Tragically) Hip receive, each time we play together, is a connection; with each other; with music and it’s magic; and during the shows, a special connection with all of you, our incredible fans.

"So, we’re going to dig deep, and try to make this our best tour yet. We hope you can come out and join us this summer - details and dates will be coming this week (beg23May16). And we sincerely thank all of you, for your continued love and support."

The band have been most successful in their native Canada, racking up two number one singles and nine number one albums. They have also enjoyed limited success in the U.S., with their 1993 single Courage reaching number 16 in the Billboard Rock Chart.

The group's success in their homeland has led to them being honoured at Canada's Juno music awards 14 times and earning their place in the country's Music Hall of Fame in 2005.

Their latest album, Man MAChine Poem, is due for release in June (16).
