James Corden‘s “Carpool Karaoke” series is one of the best things to happen to late-night TV in awhile. And last night, it got another strong co-sign with an appearance by singer and songwriter, Sia.

The episode starts with a typically be-wigged and be-bowed Sia gets picked up by a very lost James Corden. The pair proceed to tear through hits like “Chandelier,” “Diamonds,” “Elastic Heart,” “Alive” and “Titanium”.

During the ride, Sia talked about her signature black-and-white wig and touched on her past struggles with alcoholism and drug addiction. “I was a singer for 10 or 11 years to mediocre success, and I was an alcoholic and a drug addict,” she said. “I sobered up and decided I didn’t want to be an artist anymore because I was starting to get a little bit famous and it was destabilizing in some way.”
