Jazz Fest has been focused on New Orleans music and heritage from its start in 1970. But there are a number of national acts who fit right in at the festival -- and Stevie Wonder is one of them. In 2008 and 2017, he played Jazz Fest as a headliner. But at the height of his career in the 1970s, he made two very memorable impromptu appearances. Watch above to find out more, and hear parts of his songs with The Meters and Ella Fitzgerald.
