The identical twins Mark and Clark Seymour have been playing the piano since they were 4 years old. When they were 16, their parents bought a second piano, and the twins decided to put the two musical instruments together. It was then that they became an act. Their first album, “Double Take,” on Columbia Records, went gold in five countries in Europe. Three decades later they were contacted by CBS in the Netherlands, to film a special TV show there for New Year’s Eve 2008. The reason being, that they were still in the top 100 (year-end list) of the charts over there, with their 1977 CBS hit single “The Worn Down Piano” (duration 8:10).
