5 Seconds of Summer's Carpool Karaoke: Watch

5 Seconds of Summer keep anything but calm in their DIY “Carpool Karabloke” segment.

On their hourlong commute to Apple Music’s Culver City, Calif., offices to visit Beats 1 host Zane Lowe, the Aussie pop-rock group jammed out to their entire new album Calm, which arrived Friday. Frontman Luke Hemmings mimicked typical Carpool Karaoke host James Corden by doubling as the interviewer, introducing his bandmates as “an up-and-coming band. They are 5 Seconds to Mars — I mean, 5 Seconds of Summer.”

He teased the 18-minute webisode as the kangaroo edition of Corden’s Carpool Karaoke, before drummer Ashton Irwin dubbed it “Carpool Karabloke,” playing on the Australian slang term “bloke.”

But what might’ve topped the impromptu start-to-finish listening party were the comedic interludes in the car, which served as the literal butt of the joke. As Irwin “had too many espressos, and I haven’t had a chance to take a morning poop,” guitarist Michael Clifford echoed his sentiments by using the vehicle’s realistic sounding fart-noise-making buttons to the rest of the group’s surprise.

Hemmings shouted, “Oh the coffee has kicked in!” right as the second track “No Shame” started playing before he announced from an imaginary call, “It’s the second-best song, this just in.”

5SOS also snuck in a shout-out to Liam Payne by playing his top 10 Hot 100 hit “Strip That Down,” as 5SoS toured with Payne and his One Direction bandmates from 2013 to 2014.
