November was a good month for 5 Seconds of Summer. An exceptionally good month.

The Aussie pop-rock outfit saw their sophomore set Sounds Good Feels Good storm straight into the top spot on the U.K., U.S. and Australian album charts. And with that hot start, the four-piece joined Men At Work and AC/DC as just the third Australian act in history to have simultaneous No.1 albums in those three markets.

They also became the only band -- not vocal group -- to see its first two full-length studio albums debut at No. 1 on the Billboard 200 chart. Last week, the group won the “live act” category at the ARIA Awards and they used the platform of the ceremony to announce another homecoming tour for late 2016. 

5SOS managed to squeeze another few good times out of that astonishingly good month. They brought that all-conquering spirit to The Late Late Show overnight, where they performed "Hey Everybody," a catchy new song the lads delivered on stage a week earlier at the 2015 American Music Awards. Watch their late night performance below.

The Sydneysiders -- Luke Hemmings, Michael Clifford, Calum Hood and Ashton Irwin -- also sat for an interview with their British host James Corden and appeared in a sketch which revisited an earlier incarnation of the band as a five-piece (no prizes for guessing who the "lost member" was).
