British rockers THE DARKNESS have released "Masters Of The Universe", the theme tune to this year's long-awaited He-Man movie of the same name.

The track was written by frontman Justin Hawkins and his brother, guitarist Dan Hawkins, who also produced and mixed the song.

Daniel Pemberton, composer of the film's soundtrack, collaborated with THE DARKNESS on the track.

In a statement, the band exclaimed: "When He-Man asked whether we could provide some music for his forthcoming biopic 'Masters Of The Universe', we dusted off our trusty loincloths, assembled in the courtyard of Castle Darkness and bellowed in unison WE HAVE THE POWER.

Also, Brian May was there." 'Masters Of The Universe' is now available to stream/download on all major digital music services.

Meanwhile, Lakeshore Records released the first song from the soundtrack, "Eternia" featuring QUEEN guitarist Brian May, last week.

A full soundtrack album is set for release on June 5.

THE DARKNESS will support IRON MAIDEN at a massive Knebworth show in July, and will release a best-of collection, "Crock Of Hits", in October.

The band will embark on its largest headline tour in 20 years this December, bringing its beloved rock to arenas across the U.K.

The seven-date tour will commence at Glasgow OVO Hydro on December 8 and finish with the band's debut headline performance at The O2 in London on December 16.
