James Corden should just have a "Carpool Karaoke" segment every night, because they're always amazing.

Elton John was the latest musical superstar to take a ride with TheLate Late Show host and belt out his own songs. There was one word that summed up John's carpool adventure: delightful.

The 68-year-old GRAMMY winner opened up with Corden about the origins of some of his most beloved songs, and even delved into the psychology behind his elaborate and bombastic outfits.

Since John never had the big, on-stage persona because he was more or less stuck sitting behind a piano, he used his dazzling wardrobe to grab the audience.

This, of course, led to John and Corden donning some elaborate boas and eccentric glasses while singing "Crocodile Rock."

While Corden has had some insanely fun, wildly popular "Carpool Karaoke" passengers in the past, it was clear that hanging out and singing with John was one of the highlights of his adult life.

"If I could tell my 12-year-old self I would be doing this, his head would explode," Corden said, beaming.

Corden's post-Super Bowl special came hours after his previous "Carpool Karaoke" guest, Coldplay's Chris Martin, rocked the halftime show with Beyoncé and Bruno Mars. Check out the video below to see Martin and Corden's super-fun road trip.
