The normally brooding Alkaline Trio singer appeared to be very in-the-moment, smiling and playing off both Hoppus and Barker. And when it came time to sing lead vocals, Skiba delivered DeLonge's lines with relative ease, with a delivery similar enough to DeLonge's to keep the songs from sounding jarringly different yet with enough of his own personality injected to let the audience know he wasn't trying to be DeLonge.

Absent was the funny back-and-forth between the co-frontmen that fans are accustomed. But Hoppus made sure to deliver up a healthy does of potty humor leading sing-alongs for both "Happy Holidays, You Bastard" and, well, the other song that can't be described without being completely censored. You know the one. It's the one written to upset your mom.
