In a somewhat odd selection process, each of eight songs was performed twice by different artists and a public vote chose the best song.
She started her career singing with dance orchestras around the city of Haarlem, then sang on various radio stations before her first hit record, "Ik zal je nooit meer vergeten", in 1958. In 1960, Palmen took part in the Dutch Eurovision selection, with the song "Wat een geluk" ("What luck"). A professional jury then decided which of the two artists would take the song to Eurovision.
"Wat een geluk" was duly chosen as the song, but in the head-to-head with Rudi Carrell, Palmen lost out.
The song "Geen ander" ("Nobody Else") was chosen to go to the eighth, held in London on 23 March. Before the contest however, the lyrics to the song were completely rewritten, and it became "Een speeldoos" ("A Musical Box").
From a field of 16, "Een speeldoos" was one of four songs (the others being the entries from Finland, Norway and Sweden) which failed to score. This was the Netherlands" second successive "nul points" showing, following that of De Spelbrekers the previous year.
In 1967, Palmen became a featured singer with the Boertjes van Buuten orchestra (Boertjes van Buuten is a hypocorism for Little farmers from outside towns) on the monthly television programme Mik for channel KRO, playing the role of Drika.
This was a success and raised her profile. However, after the cancellation of Mik in 1972, Palmen dropped out of sight. Palmen died in Beverwijk on 15 January 2000, after a long illness of an undisclosed nature, aged 73.
