A newly created duet between Elvis Presley and Michael Buble titled "Fever" has officially been released.

The track is featured on a new posthumous collection from The King titled If I Can Dream, which is due out on October 30.

The release features 14 original Elvis recordings with new editions from collaborators as well as the U.K.'s Royal Philharmonic.

Speaking of the project, Elvis' ex-wife Priscilla Presley said it truly would've been a dream come true for The King.

"This would be a dream come true for Elvis," said Priscilla. "He would have loved to play with such a prestigious symphony orchestra.

The music . . . the force that you feel with his voice and the orchestra is exactly what he would have done."
