Olivia does get attached to her managers
Olivia Newton-Joba does get attached to her managers. When Lee Kramer was handling her career, he was also the man who dominated her personal life. After they ended their professional and personal relationship, she became involved with her young “Xanadu” co-star Michael Beck. But now Michael’s out and reportedly very much in is her new manager Roger Davies, who learned the ropes as Kramer’s business aide.
While Olivia and Lee Kramer being an item for some time is a known fact, and before that she was romantically linked with Bruce Welch who was instrumental in some of her early UK success, this hack perhaps mixed up Xanadu dancer Matt Lattanzi with Michael Beck.
Roger Davies did work for Lee Kramer, apparently from 1979. According to Milesago (archived with the National Library of Australia). After the parting of the ways between Kramer and Olivia Kramer moved on from the business and Roger Davies took some accounts over, including Olivia. Roger Davies managed Olivia for her biggest hit album, Physical and the subsequent sellout tour.
