Swiss music group from Bern. Formed in 1968 by Peter Reber, Sue Schell and Marcel Dietrich. Peter, Sue & Marc represented Switzerland four times at the Eurovision Song Contest (ESC): 1971 with a song in French (12th place), 1976 in English (4th place), 1979 in German (10th place) and 1981 in Italian (4th place). This makes them the only participants in the competition who competed in four different languages for their country and the group that has taken part in the ESC most often for a country. Rolf Zuckowski wrote and produced the band's great successes between 1975 and 1981. Peter, Sue & Marc released their self-composed songs on their own label [l152122]. The group disbanded in 1981.
