Teach-In was a Dutch pop group formed in 1969 and stayed together until 1980. The band saw many changes to its personnel over the years (like German band Wind in the 1980s). In 1971, Austrian-born singer Getty Kaspers joined the group when they got their first recording contract.
They represented the Netherlands at the Eurovision Song Contest 1975 in Stockholm with the song Ding-a-Dong. They ended up winning, becoming the first act to win performing first in the running order as well as the first winners under the new 12-point scoring system that is still being used today. The song also became a modest hit across the continent, even peaking at #22 in the American easy listening charts.
Getty left the group in early 1976, but returned to the Eurovision stage in The Hague to present the Grand Prix to her successors, Brotherhood of Man.
The group reunited to sing their winning song at a concert in Maastrich in 2007, as well as during the "Rock the Roof" interval act at the grand final of the 2021 contest in Rotterdam.
