"Lillian Roxon's Rock Encyclopedia" was one of the first of its kind. My poor paperback copy is (quite literally) falling apart. If I didn't have such fond memories of it, I would have thrown it away a couple of decades ago. When I reserved a copy originally through the Inter-Library Loan system, the local librarian told me, when it arrived, that he thought it would be a scientific tome - that's how unusual a book on rock music was at that time. Now well out of date, "Lillian Roxon's Rock Encyclopedia" always seemed to be "authentic" in some way.
Anyway, there's TV programme about Lillian Roxon coming up on Sky Arts 1 on 13 August 2013 at 10 pm.
Meanwhile, here's a little bit of Lillian Roxon from her Wiki entry:
Linda McCartney (then Linda Eastman) was one of Roxon's closest female friends and she did much to further Eastman's career, but the friendship ended abruptly in 1969 when Eastman moved to London, married Paul McCartney and cut all ties with all her former friends, a move which wounded Roxon deeply.
Lillian eventually retaliated, four years later, with her famously scathing review of the McCartneys' first American TV special. Published in the New York Sunday News on 22 April 1973, Roxon's review panned the documentary and poured scorn on Linda, slamming her for being "catatonic with horror at having to mingle with ordinary people", "disdainful if not downright bored ... her teeth relentlessly clamped in a Scarsdale lockjaw", and "incredibly cold and arrogant".
