John Mellencamp and Bruce Springsteen have joined forces for their first ever duet

John Mellencamp and Bruce Springsteen both have discographies stretching back to the '70s and have previously collaborated onstage, but only now have they recorded in the studio together.

As a teaser of Mellencamp's upcoming 25th studio album, the music legends released their first ever duet called 'Wasted Days.'

The acoustic-led track sees the singers trade off verses, before coming together for a powerful chorus.

While a mournful song, it also carries an important message about making the most of the years, months and minutes we've got left.

Mellencamp's album is expected to be released in 2022.
