Behind the scenes: MKTO's "Classic" music video
The boys explain that the clip, which sees them looking sharp in dinner suits, is about "bringing back the classic feel".
"The whole concept is about going back in time and reliving those great classic moments," Tony Oller says in the behind the scenes clip.
Check out what the lads got up to when shooting the music video, which you can watch here.
"Classic" is MKTO's second single, following their massive hit "Thank You", which peaked at #2 on the Australian singles charts.
