For the longest time, I couldn't find the Chiefs SB song that I heard on the Super Bowl Opening Night show. It wasn't Tech. It wasn't Mac Lethal. It wasn't Melissa Ethridge or any of the ones I could readily find. Anyway, after searching again tonight, I found it! Hopefully, you enjoy it as well.

It's by PL, who isn't even a KC fan. He does music for NFL Network and, I believe, does a newer version post-Super Bowl. Anyway, this was the version used on the telecast and I was, FINALLY, able to hunt it down.
