Never knew much about her beyond that one TopPop clip someone posted years ago, the blue suit, Weekend playing in the background. Kept coming back to it on youtube, not even a fan really, just liked how strange and good Dutch pop got in the seventies. Found out later the Sound and Vision museum over there actually kept that exact suit. Anyway. 79. Didn't know about the Parkinson's until today. Edit, looked it up, Seasons was written by the Golden Earring guy, didn't know that either.
Their story
Christina Henriette Kaagman, known to everyone as Jerney, was one of the defining voices of Dutch pop and rock. As lead singer of Earth and Fire from 1969 until the band's final split in 1990, she sang on a run of hits that included "Seasons", "Memories" and the 1979 disco…
Christina Henriette Kaagman, known to everyone as Jerney, was one of the defining voices of Dutch pop and rock. As lead singer of Earth and Fire from 1969 until the band's final split in 1990, she sang on a run of hits that included "Seasons", "Memories" and the 1979 disco crossover "Weekend", a number one single in the Netherlands and several other European countries. A later generation knew her as the sharp tongued jury member of the RTL talent show Idols, and the music industry knew her as a tireless advocate for the rights and earnings of Dutch musicians.
She was born in The Hague on 9 July 1947. At the Huygens Lyceum in Voorburg she sang in the school choir and in a school band called The Rangers, and after leaving school she completed a secretarial course. For a time she led a double life: by day a neat secretary, by night a singer on stage in a leather outfit, a contrast NRC later highlighted in its tribute.
In September 1969 she was invited to join Earth and Fire, a Hague group built around the twin brothers Chris and Gerard Koerts. Her arrival changed the band's fortunes. The debut album Earth and Fire (1970) produced "Seasons", written by George Kooymans of Golden Earring, which reached number two in the Dutch charts, and "Ruby Is the One". The band's first eight singles were an unbroken string of Dutch top five hits between 1970 and 1974. "Memories" (1972) became their first number one, and albums such as Song of the Marching Children (1971) and Atlantis (1973) made Earth and Fire one of the leading names in Dutch symphonic rock, a label Kaagman herself used for their music. In the same period she also sang in the one off supergroup Holland, which released the single "Hans Brinker Symphony" in 1971.
As the band moved toward pop, it scored its biggest international success with "Weekend" (1979), with its instantly recognisable marimba opening. Kaagman's performance of the song on the AVRO television show TopPop, wearing a metallic blue suit designed for her by Carla van der Vorst, became one of the most iconic images in Dutch television history. In 2013 she donated the suit to the Netherlands Institute for Sound and Vision.
Earth and Fire split in 1983. Kaagman released two solo albums, Made on Earth (1984) and Run (1987), and in May 1983 appeared in the very first issue of the Dutch edition of Playboy. Earth and Fire returned in 1987, released the album Phoenix in 1989 and stopped for good in 1990.
Her second career was as an organiser and lobbyist for popular musicians. She was chair of BV Pop, the professional association of pop musicians, which also created the annual Popprijs. In the 1990s she worked as public relations manager at Radio Noordzee, the station that later became Qmusic, and from 1 November 2000 she was director of the Conamus foundation, later renamed Buma Cultuur, which promotes Dutch music at home and abroad. From these posts she lobbied in The Hague for better rights for pop musicians, argued that Dutch radio played too many foreign acts, and supported measures against illegal downloading. On 26 December 2008 she announced on Radio 1 that she was leaving the music industry, and she stepped down at Buma Cultuur in March 2009. At her farewell reception she was appointed a Knight of the Order of Orange-Nassau.
From 2002 to 2008 Kaagman sat on the jury of Idols on RTL. Her frank, cutting and carefully reasoned verdicts made her one of the most talked about figures on Dutch television, and contestants such as Jim Bakkum later paid tribute to her as a special and unique person.
From 1974 she shared her life with Bert Ruiter, the former Focus bass player who joined Earth and Fire in 1978 and went on to produce her solo work. They never married. Ruiter died in March 2022, and after his death she withdrew further from public life.
In October 2012 Kaagman revealed that she had Parkinson's disease. She chose to speak openly so that she could be an example to others, and for some time she worked as an ambassador for the Dutch Parkinson's association. Later honours included the Hans Kosterman Prize (2016) from the rights organisations Sena and NORMA, for her work on musicians' copyrights, and a Lifetime Achievement Award in 2023 recognising both her singing career and her decades of work for pop musicians.
Jerney Kaagman died on 31 July 2026, aged 79, after a long illness with Parkinson's disease. Her family announced her death on 6 August 2026, and her funeral took place that same day in a private ceremony, at her own request. Tributes came from across Dutch music and television, remembering a unique voice, a style icon and a fierce champion of the musicians who came after her.
