Wang Chung (originally spelled Huang Chung) was a British new wave act that formed in London in 1980. The group was comprised of Jack Hues (born as Jeremy Ryder) on vocals and guitars, Nick Feldman on bass, and Darren Costin on drums (though he left the group in 1985). Named after the first note in the Chinese classical musical scale, the band released their first LP in 1982, using the original spelling. However, it was 1984's Points on the Curve that put them on the map (in the U.S., at least), as "Don't Let Go" and "Dance Hall Days" became top 40 hits.
The band continued to have success in 1985 with the soundtrack of To Live and Die in L.A, but 1986's Mosaic contained their biggest hits, with two top 10 singles -- "Everybody Have Fun Tonight" (#2) and "Let's Go" (#9).
Unfortunately, Wang Chung's 1989 LP, The Warmer Side of Cool did not do particularly well, and the band broke up in 1990. The did re-form in 1997, and remain together as of this writing.
Now, as to the video ... The clip was directed by the famous duo of Godley and Creme, who opted for a strobe effect of rapid cuts. Unfortunately, someone at the BBC became concerned that this cause trigger epileptic seizures, and the network banned it on health grounds.
