Hendricks was born in Caledon on 7 February 1936. He started his music career as a member of the Kay Simmers Orkes (Afrikaans for orchestra or band). Later, he founded his own band, Bobby Hendricks Sound. In the early 1980s his first record was released, and in the next two decades he had five gold albums.
In 1999 Hendricks died in Cape Town from kidney failure. In 2000, the Western Cape Department of Environmental and Cultural Affairs awarded him posthumously for his exceptional contribution to the entertainment business. The award was accepted by his widow, Coee. In the same year, the municipality of Caledon decided to name a street after the popular musician.
