Shelley in a candid pic from 1979
Shelley became Angel no. 5 in 1979 and joined Jaclyn Smith and Cheryl Ladd (and occasionally Farrah Fawcett) in the 4th season of Charlie's Angels. Upon the announcement of her casting, she was hounded by the media. Everyone wanted to know everything about Charlie's newest Angel. In Australia, the fact that she went there to study Archeology at the Sydney University became a news item. In 1968, upon reaching her junior year at Smith, she decided to take a year off and study archaeology at the University of Sydney; but she wanted her trip to be credited as part of her college curriculum. Her parents gave her permission to go, but the college dean went, "What?" Shelley recalled, "I told him I wanted to get away for a year on my own bat and Smith College had a fit." The dean never heard of Sydney University and, at first, wanted her to leave and not give the remainder of her tuition back. But she was able to justify her decision, and, in the end, the school gave her credit for the course. Six months after she graduated, the dean of Smith College wrote to Shelley for advice on programs similar to hers for girls who wanted to attend Sydney University. And later still, Smith College proudly informed her that they had hired a president from Sydney University.
