James Corden has had some of the biggest names in music—past and present—belting out tunes in his Carpool Karaoke car. Over the years, the segment has skyrocketed in popularity, racking up millions of views with each new guest. But even in its early days, Carpool Karaoke was already pulling in musical legends. Case in point: just six episodes in, Corden landed none other than Stevie Wonder for a singalong session through the streets of LA.

As they cruised around, the duo jammed to Stevie’s classics like “Superstition,” “Isn’t She Lovely,” and “Signed, Sealed, Delivered,” all while cracking jokes along the way. But the most unforgettable moment came when Stevie surprised Corden’s wife with a phone call. At first, he playfully spoke to her in an exaggerated English accent, but then the mood shifted. In a heartfelt twist, Corden was brought to tears as Stevie serenaded her over the phone, crafting an impromptu love song in his signature soulful style.

The video quickly became a viral sensation, amassing over 56 million views and counting. Fans couldn’t get enough of Stevie’s legendary voice, with one commenting, “Stevie Wonder’s voice is still golden after all these years.” His effortless charm also stole the show, with another viewer declaring, “So basically Stevie is the coolest, most laid-back person alive.” And it’s safe to say Corden felt the same—before parting ways, he shook Stevie’s hand and summed it up perfectly: “You’re the best, man.”
