Watch: The Killers release video promoting McGregor v. Mayweather

Brandon Flowers and the band perform the song in a boxing ring in the middle of the Nevada desert. The video also features footage of the Dublin UFC sensation and American boxing legend.

In a statement, Flowers said "I think there's a symbiotic relationship between using a song like ours and Las Vegas and a boxing arena. It seemed to make sense. Business of boxing."

"Oh, you want to use our song? We want to be in a ring too," he added. "You know what I mean… and I just wanted an excuse to wear this suit again. Really the main reason."

The Killers' Wonderful Wonderful is out September 22.
