Plácido Domingo is lending his gigantic voice to a titanic insta-classic song…

The 70-year-old Spanish tenor—who was recently named a recipient of Israel’s prestigious Wolf Prize—will duet with Celine Dion on the 43-year-old Canadian songstress’ iconic No. 1 song “My Heart Will Go On.”

The Domingo-Dion duet on the theme song from Titanic—which will be re-released in 3D this spring—is part of two new soundtracks being issued to commemorate the 100th anniversary of the ship’s sinking: Titanic Anniversary Edition and Titanic Collector’s Anniversary Edition.

The first version includes a 12-page booklet and vintage stickers, the remastered soundtrack, previously unpublished recorded music by orchestra I Salonisti and the Dion/Domingo duet.

The Collector’s Edition comprises of the booklet and stickers, along with four CDs: the remastered soundtrack, “Back To Titanic” remastered, I Salonisti’s music, the Dion/Domingo duet and popular music from the “Titanic” period.

Since its release in 1997, the original soundtrack has sold more than 26 million copies worldwide. Dion’s “My Heart Will Go On,” meanwhile, has moved more than six million copies and has become her signature song.

Sony Classical will release the two new editions of the original soundtrack to Titanic on March 26. Meanwhile, Titanic 3D is set to open in theaters nationwide on April 4.
