Jason Sudeikis Joins Mumford & Sons to Sing Ted Lasso Theme at MSG

Jason Sudeikis surprised concertgoers at Madison Square Garden on Tuesday, August 11, 2026, by joining Mumford & Sons onstage to belt out the Ted Lasso theme song. The unexpected cameo coincides with the recent Season 4 premiere of the Apple TV+ comedy, marking another high-profile promotional appearance for the star.

Madison Square Garden Crowd Surprised by Surprise Duet

Fans packed into New York City’s Madison Square Garden on Tuesday night received an impromptu musical collaboration when Jason Sudeikis joined Marcus Mumford and his bandmates midway through their concert. Dressed casually in a baseball cap, black hoodie, and khaki shorts, Sudeikis was initially spotted by audience cameras nodding his head from the crowd before sprinting onto the stage.

As the band launched into the opening notes of the beloved television theme, Sudeikis shared a microphone with Mumford to sing the familiar tune. The performance culminated with the pair singing the final line together and embracing as the audience erupted in cheers. Live Nation NYC and concertgoers captured footage of the collaboration, which quickly spread across social media platforms.

Stage banter followed the performance, with Mumford warning the New York crowd to quiet down or I’m going to stick Ted on you. Sudeikis then waved to the audience and headed back into the crowd.

How a Long-Distance Friendship Forged a Television Anthem

The partnership behind the television opening track stretches back well before the sports comedy became a global streaming phenomenon. Mumford and Sudeikis first forged a friendship in 2012 when the English band appeared as the musical guest on Saturday Night Live, where Sudeikis served as a writer and cast member before departing in 2013.

Explaining their creative connection, Mumford previously noted that Sudeikis shares a distinctively British sense of humor despite his status as an American comedy veteran. When the series was first coming together, Mumford and composer Tom Howe assembled the show’s signature theme in a 24-hour period at Mumford’s home, aiming for a natural, unoverproduced feel.

The request for the theme song itself arrived through an unconventional channel.

which I don’t keep on when I’m in the U.K. So I actually missed it, and it had been in my phone for a couple of months, and he thought I was just ghosting him. So when I finally picked it up, I called him and was like, ‘So sorry, man, but I’d love to talk more about your TV show.’

Promotional Blitz Meets Fourth Season Return

The new episodes arrive more than three years after the third season concluded in 2023, a point where Sudeikis had initially intended for the series to end permanently.

The fourth chapter finds the titular coach returning from Kansas City to Richmond, where he is tasked with leading a second-division women’s soccer team. Sudeikis has embraced high-profile cameos to support the release, including a surprise halftime appearance in July alongside Brendan Hunt during the 2026 World Cup Final, where he delivered a pep talk to Justin Bieber.

A Star-Studded Night at The Garden

Sudeikis was not the evening’s only unexpected visitor. During the concert, Mumford also brought out Oscar Isaac to perform Fare Thee Well (Dink’s Song), a traditional track from the soundtrack of the 2013 Coen Brothers film Inside Llewyn Davis. Mumford composed music for the movie, which starred Isaac and featured Mumford’s wife, Carey Mulligan.
