Apple CEO Tim Cook wasn't the most obvious name you'd expect to share a ride with James Corden for his Carpool Karaoke.

But it was nevertheless an innovative way to make the eagerly anticipated iPhone 7 announcement and Corden wasn't about to refrain from his comic comebacks as the Apple boss hitched a lift to the auditorium where he was set to make the official announcement launching the new iPhone model.

Hinting at all that was to come, Cook kicked off the three-and-a-half minute video saying : "We're going to talk about some great stuff."

"That just sounds like a press release," Corden quipped before launching into a pep-talk for the renowned public speaker ahead of his presentation that was to be watched by millions.

The Late Late Show host joked the Apple boss should walk on to the stage carrying a cane "with the Apple logo on the top." "This is a big deal," Corden said. "If I was you, I'd be wearing a suit made entirely of apples."

As the pair donned flashing neon sunglasses, Corden said: "You're changing up Apple already."

But Cook wasn't about to get away without taking part in a customary sing-song despite his lack of musical credentials. When asked about his favorite band, Cook replied that he "love[s] One Republic" prompting the pair to launch into a renditions of One Republic's "I Lived," with Cook singing with gusto, followed by Lynyrd Skynyrd's "Sweet Home Alabama, before Pharrell Williams jumped into the back seat of the car to join the party.

Corden sent him off with some good advice before his big speech. "Confidence and apple jokes." He said, adding: "I'm rooting for you."

The appearance on the show was no accident of course, following an announcement earlier this year that Apple Music had purchased the rights to a stand-alone "Carpool Karaoke" series.

With a 16 episode order, Apple will distribute the series to its members in 100 countries across the globe. The series is set to premiere in early 2017, according to a report by Variety.

Past Carpool Karaoke guests include One Direction, Justin Bieber, Jennifer Lopez, Elton John, Rod Stewart, Stevie Wonder, and Mariah Carey. Most recently Corden was joined by First Lady Michelle Obama, who was seen jamming with rapper Missy Elliot.

Cook later revealed that the The new iPhone 7 which, among other features, will be water-proof and no longer includes a headphone jack.
