A-ha - Take On Me (1984)

A-ha (stylized a-ha; Norwegian pronunciation: [ˈɑːhɑ]) was a Norwegian pop band formed in Oslo in 1982. The band was founded by Morten Harket (vocals), Magne Furuholmen (keyboards) and Pål Waaktaar (guitars). The group initially rose to fame during the mid-1980s after being discovered by musician and producer John Ratcliff, and had continued global success in the 1990s and 2000s.

A-ha achieved their biggest success with their debut album, Hunting High and Low, in 1985. That album peaked at number 1 in their native Norway, number 2 in the UK, and number 15 on the U.S. Billboard album chart; yielded two international number-one singles, "Take on Me" and "The Sun Always Shines on T.V."; and earned the band a Grammy Award nomination as Best New Artist. In the UK, Hunting High and Low continued its chart success into the following year, becoming one of the best-selling albums of 1986. (http://en.wikipedia.org/wiki/A-ha)

The first version of the song "Take on Me", released in 1984, was promoted by a now-rare video of the band performing the song in front of a blue background.
