The Scotish-Dutch mezzo-soprano, presenter and voice teacher, Caroline Kaart (neé Caroline Paterson Raitt), lived in the Netherlands at the end of the 1950’s, after she had married the 11 years older tenor and actor Hans Kaart. He, however, died in June 1963 after a failed ear surgery in Lugano, Switzerland. Caroline Kaart was living in the Netherlands and was a presenter in musical television, called "Een liedje met Caroline" (A song with Caroline), which was directed by Willy van Hemert. With him she married in 1969 and eight years later, in 1977, again separated from him.
