On Monday, Harry Connick Jr. made a special appearance on the TODAY show to teach Hoda Kotb, Jenna Bush Hager, and guest co-host Meredith Vieira how to play the keyboard.

Of course, the New Orleans native couldn't resist talking about his beloved football team to kick things off. "I was booked on this day before the Saints game, and I was gonna come either way and I was still going to teach you how to play 'When the Saints Go Marching In,' but I sure am glad we won," he jokes, speaking of the previous evening's nail-biting game against the Philadelphia Eagles. "I was watching at home with my wife and it was very focused, very intense, like my kids were afraid to come in the room."

Then the singer proceeds to teach Vieira how to play the keyboard in a hilarious segment in which Vieira manages to achieve only 2% accuracy in her lesson. The musical lesson comes courtesy of Playground Sessions, a piano learning software in which Connick Jr. is an investor. (We'll attribute Vieira's flop to stage jitters and not the program's capabilities.)

"Thanks for hanging with us, and are we going all the way?!" Kotb — who lived in NOLA in the '90s — exclaims as a send-off to the star. "Let's beat the Rams first," Connick Jr. jokes back. Watch the full video clip below.
