Kenny Rogers & Gladys Knight "If I Knew Then What I Know Now"

While the halftime show gets all the attention tonight, don't forget about the voice behind our National Anthem. You may remember Whitney Houston turned her rendition of "The Star Spangled Banner" at the 1991 Superbowl into a #1 song on the radio at a time when the world waged war in the Persian Gulf. Tonight, Gladys Knight takes her turn at Superbowl LIII.
