ESPN's exclusive coverage of 33 college football bowl games will feature extensively an original song by two-time Grammy Award-winning musician Nelly. The song, "The Champ," was written by Nelly specifically for the network's game and studio shows. It will make its worldwide debut on Saturday.

"'The Champ' brings together two of my favorite things -- music and sports. I've watched football and ESPN my whole life so to do this song was a real privilege," Nelly said. "I hope it gets champions everywhere hyped for their big day!"

A snippet is below, and the full version of "The Champ" will be available for purchase as a single on iTunes beginning on Tuesday.
