Released in 1985, A-ha’s synth-pop smash wasn’t the instant hit that many believe it to be.

It was originally called Lesson One; the song was conceived around 1981/82, when the members of A-ha were in another band called Bridges.

It was first released in 1984, but only sold 300 copies, and a remix didn’t help as it also failed to enter the charts, before the 1985 release, which is the one we all know.

The music video is as well-known as the song, and it features an rotoscope music, which required 3,000 hand-drawn frames, and evolved from an early demo of Lesson One. It took four months to complete. In 2020, it hit the Youtube 1 billion views mark.

It peaked at number 2 in the UK singles chart.
