HALO's Iconic Theme Was Based Off A Song By The Beatles

Literally any time I'm in a place that has a decent echo I bust out the Halo theme? Does that make me weird? Probably. Even so, there's no denying the catchiness of this immortal theme and it's place in the greatest video game theme songs of all time.

IGN had a chance to speak with the series composer Marty O' Donnell about how it all came about, and how The Beatles "Yesterday" is connected to the song!
