Teach-In was a Dutch band, best known for winning Eurovision Song Contest 1975 with the song " Ding-A-Dong". The band was founded in 1969 and parted in 1980. Throughout this time there were several changes in line-up.

A teach-in is similar to a general educational forum on any complicated issue, usually an issue involving current political affairs. The main difference between a teach-in and a seminar is the refusal to limit the discussion to a specific frame of time or a strict academic scope. Teach-ins are meant to be practical, participatory, and oriented toward action. While they include experts lecturing on the area of their expertise, discussion and questions from the audience are welcome. "Teach ins" were popularized during the U.S. government's involvement in Vietnam. The first teach-in, which was held overnight at the University of Michigan in March 1965, began with a discussion of the Vietnam War draft and ended in the early morning with a speech by philosopher Arnold Kaufman.
