Cramer made his television debut in 1966 with his backing group the Spaklings, and was spotted by singer Annie de Reuver, who helped him obtain a record deal. In 1967, his first single, "Zai zai zai", became a hit, reaching #7 on the Dutch chart. The follow-up "Dans met mij" also peaked at #7, and he would have a string of successful records in the late 1960s and early 1970s. His most fondly-remembered record is "De Clown" from 1971.
Eurovision Song Contest
In 1970, Cramer took part in the Dutch Eurovision selection with the song "Julia", which came fourth.

"De oude muzikant" was seen as a rather old-fashioned song, and finished the evening in 14th place of 17 entries.Cramer returned to Eurovision in 1981 with two songs, "Marianne" and "Retour", in the Dutch selection, but both finished well down the field.Cramer was associated with the 1988 Contest providing radio commentary for Dutch listeners.
