The Kelce brothers always have a good time on their New Heights podcast. But don’t think it’s all fun and games. Jason and Travis Kelce are serious performers and broadcasters who are well aware of the need for proper modulation.

After Taylor Swift smashed records last week when she appeared on their Aug. 13 pod to reveal the details about her upcoming 12th studio album, The Life of a Showgirl, the show shared a behind-the-scenes outtake on Wednesday (Aug. 20) to give Swifties a sense of the hard work that goes into sounding so good.

“Everyone knows you should always warm up before doing a podcast [laughing crying emoji],” read the caption on the post, which opens with Travis exaggeratedly saying, “Oh my gosh, Jason!,” followed by retired NFL great Jason Kelce carefully enunciating the old classic, “ow now brown cow.”

Then we see a split-screen of the brothers firing up another standard tongue-twisting exercise, “Unique, New York,” as Taylor purses her lips and the camera cuts to a close-up of her doing lip drills, trilling her lips as her voice goes up and down to Jason’s fascination. “See now that’s the…” he begins to say as Taylor continues trilling and Travis bellows, “I’M REALLY EXICTED!!!”

It’s a good thing they were warmed-up, because Swift needed her stamina to make it through the two-hour episode which featured a discussion of the new album, due out on Oct. 3, as well as the couple opening up about their personal life, first date and love story and Swift describing the emotional process of getting back her album masters.

Watch the vocal warm-up below.
