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. 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.
