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

Jason Sudeikis walked onto the Madison Square Garden stage on Tuesday, 11 August 2026, and sang the Ted Lasso theme song alongside Mumford & Sons, the band whose lead singer co-wrote it. Billboard, which reported the cameo on 12 August, described Sudeikis running around the stage, slapping keyboard player Ben Lovett, and singing the chorus face-to-face with Marcus Mumford before the two shared a hug. The Hollywood Reporter, first to publish the story, confirmed the same details. Rolling Stone also covered the appearance.
The Ted Lasso theme, titled "If I Knew," was co-written by Marcus Mumford and composer Tom Howe, with Mumford on vocals. Sudeikis is the co-creator and star of the Apple TV+ series, which returned for its fourth season in early August 2026, following the titular coach as he balances fatherhood in Kansas City with the possibility of coaching the city's new women's soccer club.
Later in the same MSG show, Marcus Mumford joked about threatening to "sick Ted on" the audience to quiet them down between songs, according to both Billboard and The Hollywood Reporter. The night also featured a second guest appearance: actor Oscar Isaac performed "Fare Thee Well (Dink's Song)" with the band. Billboard confirmed Isaac's performance.
The MSG cameo fits a recent pattern of Sudeikis appearing in character as Ted Lasso at major public events. In July 2026, he and Brendan Hunt — who plays Coach Beard on the show — made a surprise appearance at the 2026 FIFA World Cup final halftime show, which also featured Madonna, Shakira, BTS, Burna Boy, Chris Martin and the Muppets, as reported by Billboard.
For fans of the band and the show alike, the MSG moment carried a straightforward connection: the voice behind the Ted Lasso theme was standing next to the actor who plays the character it opens for, in front of a sold-out New York crowd. No special announcement preceded it. The show simply stopped, the song played, and Sudeikis — a performer best known for comedy, not music — held his own on the chorus with the man who wrote it.
