Ben Heppner to return in Canadian run of musical Titanic

World-renowned Canadian tenor Ben Heppner is returning to the stage in the Mirvish production of Titanic — his first singing role since retiring last April.

The 58-year-old singer announced his retirement earlier this year citing an "unreliability" in his voice, but it appears that the draw of the stage was too much to resist.

"Last spring I mentioned to David Mirvish that I'd love to do some acting in one of his shows," Heppner revealed in a statement Wednesday.

"I never thought that he might take me seriously...Just think, I get to sail onstage again without having to drink Isolde's poison or wear Viking horns!"

Heppner will play four roles in Titianic, including Isidor Straus, a prominent U.S. politician and businessman who goes down with the ship.

Titanic's composer and lyricist, Maury Yeston, calls the casting "an absolute coup."

"[Heppner's voice] will bring a choral glory to the evening that any composer would cherish," Yeston said in a statement.

"I look forward to this moment when musical theatre can now avail itself of what has been a treasure of the opera and concert worlds."

Titanic, which is part of the Mirvish 2014-15 subscription season, will play May 20 to June 21, 2015 at Toronto's Princess of Wales Theatre.

Over his 35-year-career, Heppner performed with the world's top orchestras and at the most acclaimed opera venues — including New York's Metropolitan Opera House, London's Covent Garden and the Vienna State Opera — both in stage productions as well as in concerts or recitals.

He has also released a number of a Grammy and Juno award-winning recordings.

Returning to the stage for Titanic won't stop Heppner from hosting his CBC Radio shows Saturday Afternoon at the Opera and Backstage with Ben Heppner.
