Gord Downie, the lead singer and lyricist of the iconic Canadian rock band the Tragically Hip, announced Tuesday he has terminal brain cancer, but still plans to join his bandmates of more than 30 years for a summer tour.

The band posted the news of Downie's illness on its website and the band managers released more details about it — an aggressive, incurable form of cancer called glioblastoma — at a news conference at Sunnybrook Hospital later in the day.

Downie was diagnosed with the disease in December and has since undergone surgery, chemotherapy and radiation.

"Since then, obviously, he's endured a lot of difficult times, and he has been fighting hard," the band said in their letter to fans. "In privacy along with his family, and through all of this, we've been standing by him."

Downie, 52, and Laura Leigh Usher have four children.

Despite the diagnosis, The Hip announced it will "dig deep" and hit the road together this summer. The details of that tour should be released later this week, according to the band.

"This feels like the right thing to do now, for Gord, and for all of us," group members said in their statement. "What we in The 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."

'I love this country'

The Tragically Hip's frontman has long established himself as one of the country's greatest songwriters, his lyrics giving a voice to Canada's land, its history and, at times, its official winter sport.

"You write about what you know," he told CBC's Wendy Mesley in 2012. "And I love this country. I love my idea of this country.

"Where I go and the people I've met, underlying everything is that commitment to finding the common good."

His music has given him a chance to bear witness to that, travelling from St. John's to Attawapiskat First Nation to Vancouver since the Tragically Hip began playing the Kingston, Ont., bar scene in 1983.

Downie and The Hip — now also including Gord Sinclair, Johnny Fay, Rob Baker and Paul Langlois — swiftly ascended from playing cover songs for Queen's University students, following a gig at Toronto's Horseshoe Tavern three years later.

That led to a record deal with MCA and the release of the self-titled 1987 EP, says the Canadian Music Hall of Fame, to which the group was inducted in 2005.

Downie's evocative lyrics didn't break out into the mainstream, however, until Up to Here, the group's first full-length album, was released in August 1989.

14 Junos

That album gave birth to the bluesy-rock single New Orleans is Sinking — which claimed the No. 1 spot on the Canadian content chart — and earned The Hip the first of its 14 Juno Awards. The Hip won Most Promising Group of the Year in 1990.

The next three full-length studio albums — Road Apples, Fully Completely and Day for Night — cemented the band members' reputation as commanders in the Canadian rock scene, as they quickly graduated to arena-sized venues and were so popular they regularly hosted their own outdoor festival, Another Roadside Attraction.

The group has been among a select few acts that could garner heavy airplay on both alternative and classic rock radio stations around the country. While Downie was adept at writing something universal like My Music at Work or more enigmatically in the case of Little Bones and Locked in the Trunk of Car, quite often the band's songs were infused with Canadiana — the hockey anthem Fifty Mission Cap, the contemplative Bobcaygeon and Wheat Kings, in part about wrongfully convicted Manitoba native David Milgaard.

Fellow Kingston native Dan Aykroyd, former Saturday Night Live cast member, was clad in a Canada sweatshirt when he famously introduced the Tragically Hip on the show in 1995 for the performance of Grace, Too and Nautical Disaster.

'One of the most captivating frontmen'

Downie channelled his lyricism inward on the band's 2012 album, Now for Plan A, released a year after his wife was diagnosed with breast cancer.

"The band, we rallied," Downie said in an interview on CBC's The Hour in 2012. "We're a big family and rallied around my wife, Laura, and helped her through it."

While the band has appealed to countless fans through their sound and the stories they've told through song, Downie's singular stage presence looms large.

The Hip's frontman can turn a microphone into a bucking bronco in one minute and a fishing spear in the next, his inimitable footwork earning him a Dora Award for choreography.

Anyone who has ever seen Downie on stage is used to his perpetual handkerchief, both a prop in his elaborate ballet — and a necessity given the stage lights, his energy and athleticism.

"His improvised antics are a major part of the show, completely transfixing the audience," the CBC's Jesse Kinos-Goodin wrote in 2013. "One performance and yet it yields, easily, 100 or more separate dance moves; such is the spontaneous genius of one of the most captivating frontmen in Canadian music."

Man Machine Poem

Although Downie has also produced three solo albums since 2001, as well as a collaboration with indie darlings The Sadies, his legacy is unquestionably tied to The Hip. The group also received the Governor General's National Arts Centre Award.

Man Machine Poem, the group's 13th studio album, will be released in June, although the single In a World Possessed by the Human Mind has already been released.

Performing for the band's legion of fans has always been one of Downie's great loves, he's told the CBC.

"Enjoy those one-night moments. We'll only be here tonight, this bunch of us in this room," he told The Hour in 2006. "Let's try and find some point of transcendence and leap together."
