The CBS Records Group was led very successfully by Clive Davis until his dismissal in 1972, after it was discovered that Davis has used CBS funds to finance his personal life, including an expensive bar mitzvah party for his son. He was replaced first by former head Goddard Lieberson, then in 1975 by the colourful and controversial lawyer Walter Yetnikoff, who led the company until 1990.
