Australian boyband 5 Seconds of Summer admitted in a recent interview that they could “write a whole book” about life on the road with One Direction, and fans are so here for it! Speaking with Zane Lowe for his Apple Music Beats 1 Radio Show, drummer Ashton Irwin got real about what it was really like to tour with the world’s biggest boyband back in 2013 and 2014.

“We started our career touring with the biggest band ever, One Direction, and that was honestly, I think we could write a whole book about that experience. I don’t know if we’re allowed to but they have a fascinating career, man,” the 25-year-old said. “I think we saw their first arena shows, and we saw their very last stadium shows together, and we saw the dressing rooms together, and we saw them apart, and we saw them from top to bottom, and it was an incredible thing to admire, and see, and watch them conquer the world like they did.”

As fans know, this came just a few weeks after 5SOS sent a major shoutout to their former tourmates and musical mentors during the music video for their new song, “Old Me.” Fans of the band will remember that if it wasn’t for Louis Tomlinson discovering them on YouTube, the four-piece group wouldn’t be where they are today.

During the interview, Ashton also explained how being on the Take Me Home and Where We Are Tours impacted their own touring style, today.

“What an insane thing to watch, and we sold about four records at the time and we had a 20-minute set and all we were doing was getting out there to play 20 minutes and then we just got to watch them play a two hour powerhouse set. It was all fascinating, and I feel like we have so many experiences and such diversity with our touring now,” he concluded.
