Stevie Wonder recently gave a surprise performance before some 2,300 graduates at Tulane University, which awarded him an honorary doctor of fine arts degree.
The Grammy-winning singer sang his hit song "You Are The Sunshine of My Life" and played a harmonica to the tune "Do You Know What It Means to Miss New Orleans" at the ceremony, which took place on Thursday, May 12.
The audience then sang "Happy Birthday" to Wonder, who celebrates his 61st birthday on Friday.
"My graduation ceremony somehow turned into Stevie Wonder concert," Twitter user mondeparfait wrote on Thursday.
"Andddd stevie wonder is currently goin IN at the tulane graduation," Twitter user six7music added. "Harmonica, piano and singin. #takemeJesus."
The New Orleans school cited Wonder's almost 50 Top 40 hits and work as a civil rights activist and U.N. Messenger of Peace as reasons for awarding the singer the honorary degree.
Other recipients included molecular biologist and Nobel Prize winner Walter Gilbert, journalist, author and New Orleans native Cokie Roberts and Pulitzer Prize-winning New York Times columnist Thomas Friedman.
