In the 1950s, Swiss accordion player Werner Thomas composed the tune to which dance craze?

The "Chicken Dance", also known as the Bird Song, the Birdie Song, the Bird Dance or the Chicken Song, is an oom-pah song and its associated fad dance is now a contemporary dance throughout the Western world. The song was composed by accordion (Handharmonika) player Werner Thomas from Davos, Switzerland in the 1950s.

The name of the original Swiss song was "Der Ententanz" (The Duck Dance). It is rumored to be a drinking song sung at Oktoberfest. Sometime in the late 1970s, the song acquired the name "Vogeltanz" (The Bird Dance) or "Vogerltanz" (Little Bird Dance or Birdie Dance), although these names never caught on seriously in Germany. On some sheet music and recordings it is called "Dance Little Bird".

In 1980, Dutch local band "De Electronica's" released an instrumental version called "De Vogeltjesdans" ("The dance of the little birds") as the B-side of a single. The A-side was not a hit, but local radio stations in the south and east of the Netherlands decided to flip the disc and started playing "De Vogeltjesdans". The record entered the Dutch charts and stayed there for over seven months, and started the international success of the song.
