Was the first halftime in a football game the product of pretty girl, distracted players and the desire to consume some Pepsi? That seems to be the case in the cola brand's 2014 'There Since the First #Halftime' 2014 Super Bowl commercial. It's revisionist history but it's cute. What's the song featured in the vintage-themed spot?

It's Bruno Mars' smash hit 'Locked Out of Heaven,' and it's used for the most cross-promotional of purposes.

Mars will serve as this year's 2014 Super Bowl Halftime performer, so it makes sense for a major sponsor of the event (happening on Feb. 2 at MetLife Stadium in New Jersey) to use the halftime performer's song in a commercial. Since, as we all know, the Super Bowl is as much about the commercials as it is about the game.

Plus, the upbeat track fits the action of good times, good soda and good girls.

Mars' fans know the song was the lead single from his 2012 release 'Unorthodox Jukebox.'
