Legend says "it's a sport that's easy to follow, and when there's the extra kind of excitement of such a big event, it's something that I definitely can watch."
Legend has even more reason to be excited about this World Cup, which begins Friday in South Africa: He is one of the performers at an all-star concert that kicks off festivities for the massive event. Other acts include Alicia Keys and the Black Eyed Peas.
Thursday's concert will be aired Friday on ABC.
